I have this bustier and ordered by Medela. According Medela-size table I need for my bra size L and fits the Medela also very good. Therefore, I have the Anita bustier also ordered in L, but that was much too small! In underbustwidth 75 I was afraid in XL easy to have no support, but starting from the tiny "cup" in L can be assumed that I would not fit XL!
Only 2 stars: The section I like (from the idea) and the fabric feels pleasant.
