READ: I bought these because they say %100 cotton! I couldn't find another pair on here that said that. Now the reviews for these underwear are terrible. But I am super impressed with them! I am very picky down there, so I had to write this review to hopefully help others out there looking for %100 cotton underwear! 1.) Buy a size up! I am a medium normally, so I bought a large. This is because cotton shrinks! 2.) Right out of the bag, these dont feel nice, but thats why you NEED to wash them first! Right after a wash they felt extremely soft and comfy! 3.) They are total granny panties but they are perfect! I am young, and I can still rock them haha. I will be buying another set!

Run small

Size: 3X-Large

I even went up a size and they were still quite uncomfortable due to being too small. They just plain didn’t fit so you might wanna go up a couple of sizes

Who knew!?

Size: 3X-Large

I have problems with elastic around my legs so I looked for underwear without the elastic and found these. Okay, not the best look for “date night” but the itchiness is gone when I wear these underwear. I consider it a miracle! Date night will just have to be à la cart.

Lil tight

Size: 3X-Large

Def purchase a size above what you normally wear. I unfortunately could not go any higher of a size. Its more of a snug fit, somewhat stretchy, but the fabric is soft and feels great. If the size was just a lil bit bigger these would be perfect. But they feel good.
