They're ok
Size: Large, Color: Set-mu2
These are ok. I'm 5'6", 150lbs. I got a large. The colors are fun. The waist band is comfortable, fits well, doesn't dig in, and sits high enough to not affect a my C-section scar, but they constantly ride up.

Bamboo Cool Camisole
Color: White, Size: X-Large
The camisole is so soft even after the first wash. It is form fitting and fits nicely under my blouses. I would definitely buy Bamboo Cool again. Arrived on time & product was what I expected. Thank you.
