Perfect toddler diaper bag
Size: One Size, Color: Black
I am a diaper bag minimalist but sometimes you just need a little extra space. This small backpack is perfect for all the essentials and more. It can easily fit a few diapers, wipes, toys and snacks along with much more. The side pockets are also able to hold things.

Comfortable and well-made
Size: 12, Color: Floral Hearts Pack
I was leery ordering these due to reviews complaining of poor sizing and construction. I wanted these for after hip replacement surgery (don't want elastic on the incision area). My pack of 3 was sewn correctly and the sizing was consistent. The cotton is of so-so quality, but it's fine. The waistband is typical basic women's underwear elastic. As was mentioned in another review someplace, these can work as shorts around the house. No one would know if they don't see the waistband. There's a crotch piece sewn in, so in that way, they're not like shorts. It should help for attaching panty liners if needed.

Comfortable and wash nicely
Size: 11, Color: Grey Jaguars Pack
I am a rotund 250. Size 11 fit pretty good but I'm tempted to get size 10 next time for a more fitted or snug fit. They loosen a bit throughout the day because they're mostly cotton but I like mostly cotton.

Stretchy and Form Fitting
Size: 16, Color: Vibrant Blue Pack
These are cotton as described, but a clingy type of cotton. I was expecting a more cottony feel but these are almost like polyester with no drape—stretchy but still cotton. The short legs always ride up on me. They seem true to size and do well when laundered.
