I just got the bra today, haven't decided if I'm keeping it yet.  You definitely want to go up at least 1 size.  From reading the other reviews, I decided to go up a cup size & a band size.  The band is very snug & the cups are small, the center doesn't lie flat.  It supports better than the average sports bra, but there is still bounce, I think if the cups fit better it would be more supportive.  It seems well made & I think it would hold up to frequent wearings & washings.
