Best Sleep Shorts EVER ♥️
Color: Multicolor a (5-pack), Size: Medium
Love, love, LOVE these bamboo BoyShorts! I wear them for sleeping because they’re incredibly light, soft and comfortable while still having a great liner. They fit to my body while not feeling tight, snug or restrictive. Soooo comfortable. I’m 5’8” 145 lbs and went with Medium. ♥️

Amazing fit!!!
Color: Multicolor a (5-pack), Size: Large
These are quite literally the best underwear I have ever worn. I am going to replace all of my underwear with just these. I got the shorter boy shorts cut and they are amazing. These let my body be the shape that my body is, no squeezing or tight waist band. I feel so normal and comfortable in them, they’re breathable and soft!! I absolutely love them after so much trial and error with underwear I finally found the ones!

Highly recommend during pregnancy and to wear around the house!
Color: Multicolor a (5-pack), Size: X-Large
Love!! I’m currently 33 weeks pregnant. I’m 5’6” and pre pregnancy weight I would fluctuate between 132-140 lbs easily. I now weigh 162 lbs and my hip is now measuring 40 inches.
I bought the XL in the dark grey/black so that it wouldn’t be tight at all around my belly and I absolutely love them! Stretchy, comfortable, breathable. They aren’t loose around my thighs and I can tell they are gonna be nice to wear during post partum. I wear them around the house with an open robe and a bralette for the ultimate comfort.
If I were to buy them before pregnancy, I’m positive that a large would have fit beautifully, even though the small/medium measurements on the size chart would have been my pre pregnancy weight, I know they would have been too tight. I detest tight underwear!
Highly recommend!

Cute and Comfy
Color: Multicolor B (5-pack), Size: Medium
These are cute and comfy with a great fit. True to size they are cool and comfortable for everyday wear. I was going to order more but the price went up so I'm just waiting for it to go back down to order again.

Not what I’d hoped
Color: Multicolor a (5-pack), Size: Small
The fabric is nice, soft without being overly bulky. The design was almost what I wanted. I’ve been trying to find underwear that won’t ride up and is comfortable to wear under leggings. The fabric has a LOT of stretch around the legs and deforms quickly. Then it rides up and wrinkles. Smaller leg openings might make the difference.
