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.

Love
Size: Medium
I am someone that really does not like to wear underwear, but I don't need to be flashing everybody. I probably should have went with some calmer prints, but they are comfy! Sometimes I forget that they are supposed to be underwear and I walk outside in them.

Size chart does not reflect actual size of garment.
Size: 3X-Large
I ordered these according to the size chart. Asian sizes are much different from U.S. sizes. What I received does not coincide with measurements given. The only good thing I can say is that the colors are pretty.

Soft and comfortable
Size: Small, Color: 5 Pack - Modal Blue/Red/Grey
My son love that these are longer on his tights than other brands that ride up. No more picking wedgies during sports! Very happy with them as a mama. My son says they are soft and comfortable and asked for me to order more!
