Best Underwear Sewing Pattern for Women, Boys, and Girls

Women's Underwear

The Uptown Undies and Camisole

The Uptown Undies Sewing Pattern is great for everyday women's underwear that provides unparalleled comfort and confidence. It includes both undies with a bikini cut and a camisole, allowing you to add a shelf bra if desired. The camisole also offers a maternity and breastfeeding option, making it even more convenient for new mothers. With this versatile pattern, you can create comfortable and stylish undergarments that meet your unique needs. Whether you're looking for support during pregnancy or want to feel confident in your everyday wear, the Uptown Undies & Camisole has got you covered.

This underwear sewing pattern comes in a wide size range from XXS to XXXL. Also, while the first version of this pattern did not include maternity/nursing, the current pattern includes both.

"I debated on buying this pattern for a very long time. It seems that I'm always searching for undies that are comfortable for me. I hate elastic around my legs and I had found a Hanes style years ago that had bands, but haven't seem them in stores for years. I finally decided to try these, even though the waist is lower than I'd like. It turns out they are so comfortable that I don't even know I'm wearing them, so I don't even notice where the waist lands! I love these and just know I'll never have to buy another pair of uncomfortable store-bought undies again!" - Mary

Girls Underwear

Classic Panties & Camisole

The Classic Panties and Camisole Pattern is perfect for providing complete coverage and comfort to young girls. It offers a comfortable fit with knit bands instead of elastic, providing snugness without compromising on the comfort of your little ones. The Classic Camisole is an excellent layering option with its simple yet charming design. Whether worn alone or under clothing, it is a versatile piece that can be styled in various ways. This underwear sewing pattern is perfect for those looking to sew high-quality, comfortable, and stylish garments for their young girls.

"My daughter LOVES this set (and so do I)! Made this and the women's version (Uptown) in matching fabrics for me and my 6 year old daughter. She loves her's and can't wait for me to make her more!!! I think eventually all her undies will be replaced with these. (And for the ladies you won't be disappointed with the Uptown for yourself, I may never go back to RTW). These sew up very quickly and can easily be done without needing a serger/overlocker/coverstitch (although i do prefer the finished look of the serger). This pattern will pay for itself I'm sure!!" - Carrie

Boys Underwear Sewing Pattern

Classic Briefs and Boxer Briefs

The Classic Briefs and Boxer Briefs underpants pattern is designed to ensure that your young boys stay covered and comfortable. This great pattern consists of both a knit briefs pattern and a knit boxer briefs pattern, both of which have the option of a faux or functional fly. The underwear is made entirely from knit fabric, without the use of elastic, in order to maximize comfort. This is a great way to use up those knit scraps.

"I purchased this to make my toddler some fun undies and the pattern didn’t disappoint. Enough options to make it useable for a long time but simple enough to whip up a few in an afternoon." - Stacey

Using PDF Sewing Patterns

Are you new to PDF Sewing Patterns? No worries...I'll explain a bit about the digital sewing pattern revolution. PDF Sewing Patterns have a lot of advantages over traditional tissue like paper patterns that you can buy in the store. First, you can re-print them as many times as you want. When you purchase a pattern from Peek-a-Boo Pattern Shop, you'll receive an account on our website where all of your patterns were will be stored. You can log into your account and print your sewing patterns as many times as you want.

Second, most of our sewing patterns - including both of the Maxi Dress Patterns featured above, include layers. This means that you only have to print the size you want. When you print the pattern, you can print it on regular printer paper which is far more durable than a tissue paper pattern. Finally, most of our patterns, including the maxi skirts, have projector files. Many people are buying projectors that they can mount from their ceiling and use to project pattern pieces onto fabric while they cut them.

Our PDF Sewing Patterns come with a full tutorial and color photos in an easy to print PDF. The Pattern pieces are computer generated and color coded for easy cutting. These Maxi Dress Patterns also include layers so you can just print off the size you need. They also include an A0 format for printing at a copy shop and a projector format.

Choosing Fabric for Your Underwear

Our three underwear patterns featured above are all best made out of knit fabric with at least 30% stretch (4-way stretch is best). One of the following fabrics would be a good choice:

1. Cotton Lycra: Our most popular fabric at KnitFabric.com is cotton lycra. It has 4-way stretch and a soft hand. It's a comfortable and versatile fabric and a very popular fabric for underwear.  
2. Interlock: Interlock fabric is a soft and stable knit and easy to sew with. Although interlock isn't as stretchy as jersey the edges will not curl when cut or stretched making it easier to work with.
