I don't recall any altering so I assume they offered them in their sizes, or they had to squeeze into a smaller size.   I’ve never been a huge fan of swimsuits. Why are they so clingy? Why do none of them support my boobs? (Oh, people “concerned” about my health, this is the part where you complain if I can’t find swimsuits in my size, that I should just lose weight.)  Not surprised, because you are too fat, because you no longer have boobs you have huge sacks of fat, and yes we will.
