I am usually a small or medium size, (34 bra size) and found this bra to be pretty comfortable but a little tight, which surprised me since it says one size fits all.  I didn't like the padded inserts and find it to look fine without them.  I still think this bra is more comfortable than a regular bra, and gives minimal support, but after wearing it all day I do have lines around my sides and back where it is just a bit to tight. I like the assortment of colors and it is very soft.
