I've been wearing the Le Mystere Whisper style bra for about a year now, and love it, so I thought it would be nice to try one of their prettier bras for special occassions.  The Isabella is a beautiful bra, and I would say it's sized the same as my other Le Mystere bras, which means a slightly tighter band than other brands.  I have to agree with the others who said the top part of the cup is too large, it didn't lay smoothly on the top of my breast, it stuck up and out.  Someone with implants probably wouldn't have this problem, since implants tend to make the bust fuller all around.  I'm 5'9" tall, weigh 150 pounds, wear a 36D bra, and have a natural full bust.  Unfortunately, I'm going to have to return this bra.
