Bought in white for my wedding my dress. Ordered it both in S and in M. Difference was not visible - in the armpits, the dress has strange "gebollt". I brought it to the tailor and 22 later it fits well. I am in the 4th month of pregnancy and 1.59 (n already have good tummy) tall. Maybe it's the size of the money to the poor / below was too large too far. Otherwise a very nice dress. I'm curious what my guests are saying :)
