Once you get the right size, this is a pretty great bra.  It stays put and is supportive, which is no small feat in an F cup.  That said, the band size is WAY off.  I own other Le Mystere bras in other styles and wear a 38F in all of them.  I ordered a 38F in this one and couldn't get it fastened because the band was so small.  I then ordered a 40F.  I can fasten it on the last hooks, but it's painfully tight.  I assume a 42F would fit, but I'm not willing to drop any more money on strapless bras.  I opted to purchase a bra extender instead.
