I bought these for my daughter who gets embarrassed by that time of month. The black hides any accidents that might stain the panties and she is very happy to no longer be embarrassed when it's time to do laundry. They are true to size and she says the fit is nice. They are nice and stretchy but not loose.

Don't even read this, click BUY NOW!

These are probably the best underwear I've owned. The material is comfortable and breathable. It isn't "jersey sheets" soft but are definitely where it's at. The waistband doesn't roll. They look expensive, the colors are beautiful. The fit was perfect. I am thick and the material doesn't stretch out awkwardly. It stretches with my body. They are very durable at the same time. Seriously though, they are extremely worth the price and you don't have to be worried in this economy you threw your money away to something that won't hold up! Love them! Even got a pack for my tween :)

I love these underwear, it’s super comfortable especially when I go to get massaged, as I feel more covered and secure. The size is perfect and i highly recommend it.

Buy them!

Color: Black&grape Purple&ash Gray&white&pink&beige, Size: Medium

I actually bought a second package before trying the first and do not regret it! These are the most comfortable underwear I've ever owned. The waist fits right and hasn't rolled once!! They're soft, stretchy, not tight and pretty lightweight. My only gripe is they're supposed to be hand washed and dried, which is on me for looking at the price and not the fine print. Won't stop me from buying more, they're that comfy and I recommend highly.
