I purchased the black in 30F. It fit perfectly. I wore it with a strapless dress for a day and everything stayed in place. I am very happy with this bra and will be buying the skin coloured one.

I have been waiting for knix to make a strapless bra, however this was not it. Not tts, the band is wayy to tight. (I get it has to be tight but its too much). I think whether this works for your particular chest will depend on breast shape. I am 34F, but my breasts are wide set, lack fullness at the top but are very bottom heavy. This style just did not work for me.

Not very comfortable . Shows through when wearing a T-shirt .
