VERY WIDE. I only dock 1 star because this bra is a lot bigger than what you'd figure from the picture..!!! If you have a low cut V neck shirt or dress, this high-cut bra *will* be seen.
LIKE A BANDEAU -- EXTREMELY comfortable and very normal looking under clothes, and actually quite flattering.
TRUE TO SIZE. I'm a 34B and both cups are perfect in size, hold their shape, and yet softly so. Very natural looking.
UNDERWIRE. There is an underwire. As I have a nickle allergy I carefully took the wire out .. and the bra still holds its shape nicely. (Other bra designs have collapsed when I've done that!!)
