These are what my daughter was looking for, a seamless underwear with invisible lines. Great product, well constructed, durable fabric.


They are very nice quality and my daughter is very happy with the underwear.

Great underwear

My daughter loves this underwear. She says it is so soft and comfortable. Her new favorite. I like how smooth they are so not so visual panty lines with her leggings. Much better than the underwear I have gotten at local stores.

Smartie pants

Great fit

Great panties for new stage

My twin 8-year olds were growing out of their kids’ panties, wanting something a little more grown up. They love the Yellowberry underwear, both because of the story behind the company and the panties themselves. The cut is a little less coverage on the cheeks than they’re used to, so initially they felt like they had “wedgies” a lot, but have gotten used to where the material lies. The material is so smooth that they often forget they’re wearing underwear, which is how it should be. For my part, I love that you can’t see the seams through their leggings. We’ll definitely continue to purchase from YB, looking forward to getting their bras when the time comes.
