Ha, I never thought that having abnormally wide set boobs would be good for something! I love cross body bags. I do have to make sure the strap length is right though - too short and it's hard to get on and off, bit too long and it's always bumping all over my big butt.
VC, I agree that they are essential when grocery shopping! The other day, I bent over to get something from a bottom shelf and my (non cross body) shoulder bag swung around and bonked me in the head.
