Great quality

My daughter loves this underwear. These are high quality, made in the USA, and made of organic cotton. I will be buying again.

My favorite underwear ever

I am an adult female size small, and these are the best underwear I have found-- they cover you without being too skimpy like many underwear made for adult women, and are very soft, the organic cotton is thick and they are durable for years of use.

Comfortable and safe

We absolutely love these underwear. It is very important for me to give my child organic cotton to cover her private parts. My father, a gynecologist, says women should always wear cotton. The organic part is important after learning concerns with pesticides in cotton, and these are some of the few I’ve consistently found. My daughter used to struggle with comfort with other brands, but she loves how these fit on her and asked me to get her more after our first pack. The colors are varied and beautiful. I wish they had same color packs for more colors. My daughter is 8yo and wears 10/12 size in clothes. She wears 12 for these underwear. So I would say they fit as expected. When the pandemic started, there were no organic cotton for older kids. They are back and I hope they continue to make them. I recommend them every time for niece and every girl.

Favorite of my daughter

Bought size 12 for my daughter who is tall and athletic at 10.5. they fit great. Also bought a few other similar style. She came to me and said I need to buy her more of these specifically as they are her favorite.
