I am very happy with my order. The dress is very nice and fits well. Natalie was very helpful and recommended correct size for me. I am 167cm and 57kg before pregnancy, 32D (34C) and usually I am between 2 and 4 US sizes in Seraphine. I ordered size 4US and it fits perfect. I would not go with smaller size. The material is not thin at all. You can wear this dress in the summer (not very hot though) or in spring/ autumn with a jacket or cardigan. I feel that it won't be too loose after pregnancy and I can wear it during breast feeding too.
