Hey everyone! Are you ready to dive into the whimsical world of Mary Poppins? Creating a Mary Poppins costume is a fantastic project for any sewing enthusiast, from beginners to seasoned pros. This guide will walk you through everything you need to know, from selecting the perfect sewing pattern to the final touches that will bring your costume to life. Let's get started and make some magic!

Choosing the Right Mary Poppins Costume Sewing Pattern

Okay, so first things first: the pattern! Choosing the right Mary Poppins costume sewing pattern is super important. There are loads of options out there, so how do you pick the best one? Here’s a breakdown to help you out:

Consider the Version: Are you aiming for the classic look from the original movie, the more modern vibe of Mary Poppins Returns, or something in between? This will significantly influence the pattern you choose. The original Mary Poppins is known for her iconic silhouette: a high-collared coat, a long skirt, and a hat adorned with flowers and cherries. The Mary Poppins Returns version has some similar elements but with a different style. The coat is often less structured, and the skirt can be a bit more flowing. Look at images from the movies to guide your vision. If you're going for the classic look, you'll need a pattern that includes a coat, a skirt, a blouse, and a hat. For Mary Poppins Returns, you might look for a slightly simpler coat and skirt pattern, or be prepared to modify a pattern to achieve the desired look.
Skill Level: Be honest with yourself about your sewing experience. Patterns are usually labeled with skill levels (beginner, intermediate, advanced). If you're new to sewing, start with a beginner-friendly pattern. These patterns typically have fewer pieces, simpler instructions, and basic construction techniques. Don't be afraid to start small and work your way up to more complex projects. If you're a more experienced sewer, you can explore patterns with more details and techniques, like complex tailoring or embellishments. If you are a beginner, it's best to start with a pattern that has fewer pieces. You could consider starting with the skirt and hat and then moving on to the more complex pieces. There are plenty of free sewing patterns online and there is also a plethora of tutorials on YouTube that can help you with sewing.
Size and Fit: Make sure the pattern comes in your size! Take your measurements (bust, waist, hips) and compare them to the pattern's size chart. It's often better to go a size up than a size down, as you can always take a garment in but not always let it out. Also, consider the style of the costume when assessing fit. Mary Poppins' outfits tend to be fitted but not skin-tight. Make sure the garment allows for easy movement, especially if you plan to dance or sing in your costume. Read reviews of the pattern online to see if others have found the sizing accurate.
Pattern Features: Some patterns include specific details like pockets, pleats, or ruffles. Decide which features are essential for your vision. If you love the idea of pockets in your coat, make sure the pattern includes them. If you adore the pleats in the skirt, look for a pattern that has them. Think about what will really make your Mary Poppins costume stand out. Are you going for the iconic umbrella or perhaps a magical handbag? These are the little extras that can take your costume to the next level!
Where to Buy: You can find sewing patterns at fabric stores (like Joann Fabrics or Hobby Lobby), online retailers (like Amazon or Etsy), and independent pattern designers. Compare prices and read reviews before making your purchase. Online stores usually have a bigger selection of sewing patterns and it's easy to compare the pattern details. Fabric stores are also a great place to buy sewing materials. Independent pattern designers can offer unique styles and often provide more detailed instructions and support.

Gathering Your Materials for Your Mary Poppins Costume

Alright, you've got your pattern. Now it’s time to gather your supplies. This is the fun part, guys! Here’s a general list of what you’ll need for a classic Mary Poppins costume, but always refer to your specific pattern for a complete list.

Fabric: The main fabric will likely be a sturdy, dark-colored fabric for the coat and skirt (wool, twill, or a similar blend). For the blouse, you’ll want a lighter fabric like cotton or linen. Consider the time of year and the climate when choosing your fabric. You'll need enough fabric to cut out all the pattern pieces, so make sure to check the pattern envelope for fabric requirements. Pre-wash your fabric before cutting to prevent shrinkage after you’ve sewn the costume! For the coat, you may want to use a fabric that is slightly heavier weight to give it structure and a more tailored appearance. It will also help with keeping the right shape when wearing the coat. For the blouse, choose a fabric that is lightweight and breathable so you can stay comfortable while wearing your costume for an extended period of time.
Lining Fabric: For the coat, you’ll want a lining fabric to give it a polished finish. A silky or smooth fabric like satin or bemberg rayon will work well. The lining fabric will make your coat look more professional and is also the best option to help the coat slide on and off easily. Choose a lining fabric that complements the color of your main fabric.
Notions: This includes all the extras: buttons (large and decorative for the coat, smaller for the blouse), thread, interfacing (to add structure to the collar, cuffs, and other areas), bias tape (for finishing edges), elastic (for the hat), and any embellishments (like ribbons, lace, or appliques). Make sure your thread color matches your fabric! Get a good quality thread that won’t break easily while you are sewing your garment. You might also need a zipper for the skirt or coat, so make sure to get the appropriate length and style. Interfacing comes in different weights, so choose one that is appropriate for your fabric. For instance, a medium-weight interfacing would work great for your collar and cuffs. Bias tape is a handy tool to help finish edges with a clean look.
Sewing Tools: You'll need a sewing machine, pins, a measuring tape, scissors or a rotary cutter, a seam ripper (trust me, you’ll need this!), a needle (for hand sewing), and an iron and ironing board. Make sure your sewing machine is in good working order and has been serviced recently. Use sharp pins so they don’t snag your fabric. A good pair of fabric scissors is essential for cutting your fabric accurately. A seam ripper is your best friend when you make a mistake, or need to unpick a seam. Having an iron and ironing board is really important for pressing seams and giving your finished garment a polished look. Ironing your seams at the different steps of sewing will give your final costume a professional finish.
Hat and Accessories: This is where you can get creative! You'll need a hat (you can buy one or make one from scratch – there are tutorials for both), ribbons, flowers, cherries, a bird (optional!), a handbag, and an umbrella. These accessories will truly make your Mary Poppins costume unique. You can find pre-made hats at costume shops or craft stores. If you are feeling crafty, you can create your own hat using felt and other materials. Ribbons and flowers will help decorate the hat in a very unique way. Consider the color scheme for the hat decorations and accessories so everything matches nicely.

Sewing the Mary Poppins Costume: Step-by-Step Instructions

Let’s get sewing! Here's a simplified overview. Your specific pattern will have detailed instructions, so always follow those closely.

Prepare the Pattern: Lay out your pattern pieces on your fabric and pin them in place. Make sure to follow the grainline arrows on the pattern pieces to ensure proper fit. Carefully cut out the fabric pieces, using sharp scissors or a rotary cutter. Transfer any markings from the pattern to the fabric using tailor's chalk or a fabric marker. Make sure the fabric is on a flat surface when you cut. This ensures that your pattern cuts are precise and makes your sewing process easier. Having a clear idea of where the pattern goes will help make this process go smoothly!
Sew the Coat: Start by sewing the coat pieces together according to the pattern instructions. This usually involves sewing the front and back pieces together at the shoulders and sides. Attach the sleeves, then construct the collar and cuffs. Next, sew the lining pieces together and attach the lining to the coat. The coat construction is one of the more challenging parts of the costume. If your pattern includes darts, sew them first to create a better fit. Iron the seams flat as you go. Attaching the collar and cuffs can require some precision, so take your time and follow the pattern instructions carefully. After attaching the lining, press the entire coat with an iron to give it a professional finish.
Sew the Skirt: Sew the skirt pieces together. This typically includes sewing the front and back panels together at the sides. If your pattern includes a zipper, insert it at the center back. Then, attach the waistband. The skirt construction is a bit simpler than the coat but you will need to pay attention to details. Make sure the seams are straight and that the skirt hangs properly. Consider adding pleats or gathers to the skirt for a more authentic look. Inserting a zipper can be tricky but there are lots of video tutorials online that can help you with the process.
Sew the Blouse: Sew the blouse pieces together, attaching the front and back pieces at the shoulders and sides. Attach the sleeves and construct the collar and cuffs. Add buttons and buttonholes. The blouse is a great project for learning basic sewing techniques. Make sure the blouse fits well and that the details like collars and cuffs are sewn correctly. Buttons and buttonholes can be a challenge. Take your time to make sure that the buttonholes are the right size and that the buttons are securely attached.
Finishing Touches: Hem the coat, skirt, and blouse. Attach any embellishments, like buttons, ribbons, or lace. Iron the entire costume to remove any wrinkles. Examine the finished product and make any adjustments needed, like adjusting the hem length or taking in the seams. When you are finished, try on the costume and make sure everything fits properly. The finishing touches are what will really make your Mary Poppins costume stand out and give it the finishing touch. This is the chance to add those extra details. The small details will make the costume even more special.

Customizing Your Mary Poppins Costume

Want to make your Mary Poppins costume extra special? Here are some ideas for customization:

Fabric Choices: Experiment with different fabrics. A luxurious velvet coat or a skirt made of a patterned fabric can add a unique flair. Don't be afraid to mix and match fabrics to get the look you want! Maybe you would like a bright red coat instead of the traditional dark colors. Make sure you use good quality fabric, whatever you decide to use. The fabric is the canvas for your creativity.
Embellishments: Add embellishments like lace, appliques, or embroidery to the coat, skirt, or blouse. Get creative with the buttons! The embellishments are the little details that will make the costume unique. They will make it really special, and they can make your costume one of a kind. Consider adding embroidery to the coat or to the hat.
Color Palette: While the classic Mary Poppins costume is traditionally dark, consider using a different color palette. A pastel or bright-colored costume can create a fresh new look. Choosing a unique color palette is a great way to make your costume stand out. Try something different and have fun with it!
Accessories: Don’t forget the accessories! A stylish handbag, a whimsical umbrella, and a hat with flowers and cherries are key. These are the details that will take your costume from good to great. Consider the details on each of the accessories, such as the umbrella handle and the shape of the bag. The accessories add that final touch to make the costume even more special.

Tips and Tricks for Sewing Success

Take Your Time: Sewing a costume can be time-consuming. Don't rush! Work slowly and carefully, and enjoy the process. Sewing your own costume can be a really fun activity. Take your time with your work and make sure to pay attention to all the details. It is very satisfying to make your own costume, so make sure you make it a great experience.
Read the Instructions: Read the pattern instructions carefully before you begin. If you're unsure about something, look up tutorials online or ask for help from a more experienced sewist. Make sure you read through the instructions before you start working on your project. If you are unsure of any of the steps, then look up some tutorials online. Don't be afraid to ask for help from someone that knows more.
Press Seams: Pressing your seams as you go is essential for a professional finish. This helps to set the stitches and give the garment a neat, crisp look. The pressing will help everything lay flat. Don’t skip the pressing! It is important to give your work a polished look.
Test Your Seams: Before you start sewing the entire costume, test your seams on scrap fabric. This will help you get the hang of the pattern and make sure your machine is working properly. Trying out the sewing pattern before you get started will give you a better idea of how everything will work. This also helps with the accuracy of your sewing and will give the costume a polished look.
Don't Be Afraid to Make Mistakes: Everyone makes mistakes! If you make a mistake, don’t worry. Use a seam ripper to undo the stitching and start again. This is a very important tip! If you make a mistake, don't let it ruin the project. It's okay to make mistakes. A seam ripper is your best friend when working on a sewing project. Don't be afraid to ask for help. Sewing can be tricky, especially if you are just starting out. Make sure to learn from your mistakes and don’t give up!
