For the price I paid, I am happy enough with this tankini top (under ten dollars).  However, I would have returned it if it had been full price,  I got an M, and am a 36A.  It fits me just fine, so I imagine anyone more blessed in the bust area would have issues.  Also, the underwire does sit awkwardly, so I plan to remove it from the top.  Lastly, the stitching around the top of the tankini is rather rough.  Don't know that this will be comfortable to wear all day.  One more thing, if this material is stretched, it gets a bit sheer, so just beware.
