I'm 53, 185 5'7" with a middle aged 41-42" bust, 38" waist and bubble behind , .. . .  This dress fit beautifully.  I normally wear a size 12, but followed the sizing chart and ordered one in 12 and one in 14.  I selected another dress for my son's weddings, but this was beautifully made and I wish I had more events to attend so I could keep it!  The 14 fit perfectly.  Very elegant.  You can't wear a regular bra at it shows in the back.
