Wardrobe staple!
These are PERFECT for summer but also will be great for layering in cooler weather. I bought 2 different packages so I have a plethora of colors to choose from. The fabric is extremely comfortable and great quality. I went with med/large because I'm a 36DD, 145 lbs and 5'6". I could've gone for the next size up, they're snug but not at all tight after wearing for a bit... and I can skip the bra! There's no side boob as they go quite high in the pit area. They're thick, not see through and fine ribbed so no visible nips. They rest right at my belly button and I'm pretty long waisted. I haven't washed them yet but not too worried because I don't dry most of my clothes anyway.

Not for me
Returned. Too flimsy, did not like the strups shape, was not flattering or supportive in any way, white one is completely see through

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.

Well made, light fabric. Waist doesn't roll.
These bamboo underwear really do keep you cool.
They fit true to size, and wear easily. the wide elastic waist band doesn't roll on me.
They are comfortable to wear, washed and dried easily.
The material has some stretch to it, but not a lot.
Well made, no stray strings. Perfect fit for me.
Just what I was looking for.
