I love these bras. I have one that was XXL(36 DD my normal size depending) and it was just too big by end of day or a few wears, I'm busty, but it would stretch, which was fine, but I went down a size for that reason. This bra is great for around the house, running to the store, or for me long days on set when I don't need to wear super dress up business clothes. Working 12 to 16 hour days these bras help me in the film industry. Add a cami with a built-in bra for a little extra support if you need it for a more professional look.

As I said it does stretch a bit, but I'm busty, smaller breast I'm sure don't weigh the cotton  materials down.
