I had a corset professionally put in (she did an amazing job) so the dress is VERY forgiving. I was a 34D at the time and it fit perfect, but would work with a smaller or larger bust/cup also. I am 110 lbs and wear Size 0/2 depending on designer, but again, because the corset goes all the way down, I would say that this dress would fit anyone between 00-4 street dress size. Tag size on the dress is 8.
I got married on the beach and did not dry clean this dress. I am including the veil you see in the photos at no cost, which also needs to be drycleaned. I am 5'1 and wore 5 inch heels.
