No returning a shirt that has been stretched this much.
I'm amazed she was able to find such a top because quite often she wears XXL men size tops. 
You would be amazed watching how much she has to stretch one of her bras, using both hands, one boob as a time, just to get it on. You hear the snap, see her grimace, and think, well, that stung. The second bra goes on a bit easier now that her boobs are squeezed together more.
