This post contains a couple affiliate links, so if you happen to buy a pattern from one of my links*, I’ll receive a small commission at no additional cost to you. This is how I afford the stupid ice cream truck that drives by my house all the time. The Popsicle benefactors and I thank you for your support:) If you’re on the fence about making unmentionables, try one of the 12 free underwear patterns in the list at the bottom of this post. You can decide if underwear is for you. (Making them, that is. Wearing underwear….that’s for everyone.)

Next, Greenstyle! Last year Edson got a big ole’ fancy truck for Fathers Day. This year I made him some Walbrook Boxer Briefs– and they’re getting as much mileage as his truck. I can’t wait to try the boys version for my nephews.

Speaking of staple patterns, here’s the girls panties version. Includes a cami top! These are great pre-training bras.

Technically gym shorts and a crop top, but I’m seeing boy-cut panties and a racerback sports bra.

Pirates Booty Boxer Briefs by PatternsForPirates 12 mos-14

This is probably the fastest underwear pattern around. Super quick, comfy, and tween approved. Patterns for Pirates has the sone of the best designs for older kids.

The Jane Knickers: Measure Twice Cut Once, women 6-18

The Jane Knickers from Measure Twice Cut Once, women's size 6-18

This is a women’s pattern, but the smaller sizes will work great for older girls. The waistband is easily adjustable too. 

Knit Hipster or Bikini Briefs from MonkeysBug Patterns, size 2-12

Knit Hipster or Bikini Brief from MonkeysBug Patterns | Top 12 Kids Underwear Patterns

The Knit Hipsters and Bikini Briefs are on my “to sew” list too. The banded waist and leg openings look super comfy. These would work with fold-over elastic. (By the way, f.o.e. is my thing now.) Shoreline Tank & Basic Brief Bottoms by Jocole, nb-14 years + 18″ doll

Shoreline Tank & Basic Briefs pattern from Jocole | Top 12 Kids Underwear Patterns

These briefs are adorable, and encased elastic method. This makes it way easy to get the perfect fit; just cut your elastic to size! The tank also makes a perfect undershirt.

Hello. I'm Amy and I'm addicted to sewing. I borderline-hoard fabric, buttons, & patterns. Sometimes I wish I could pile my fabric up on the floor and just roll in it!


  1. Amy of while wearing heels

    I don’t know if I’ll ever be brave enough to sew up undies BUT the cute knits out there kind of make me want to try :)

  2. Cindy

  4. Measure Twice Cut Once

    Thank you so much for including our Jane Knickers in such a wonderful round up of styles!

    We also have The Darcy Boxer shorts that include instructions for making both a men’s and a ladies version from the same pattern and it’s free. The smaller sizes would be good for bigger kids and tweens too.
