I'm 5'9" with a 36(more like 35)-A chest and didn't need a bra for most of my life, so I have a very hard time finding bras that both fit and are comfortable to wear all day. I find this bra fills the bill. It's supportive but not in a constricting way. I like the natural enhancement of the soft padding. Both the elastics and the lining material are very soft on the skin.  The slightly wider straps never slip!

My only real problem with it is that I'm between sizes (34B and 36A), so I have one of each and change them out depending on what top I'm wearing. The shape could be a bit more flattering, so I'm also trying out Warner's Elements of Bliss wire-free with a lace band, which has a tad more shaping, separation and lift.
