I'm not measuring each one, they are IDENTICAL in size. Princess (the blond, in above pic) was signed up for the Dive Bar Tee of the Month for at least 2 years, because I had 24 of these in my possession before I started selling them. She doesn't even like girls' tees, nor can her bought boobs fit in these. I haven't worn them all, but even the ones I have, probably just once. I mean I'm 59 and retired, what would be the occasion? But they're cool, and they all came with a neat postcard with pictures and a spill about their history. They're good quality, fit nice, and are just fun and interesting conversation pieces. If I were younger I might aspire to try to go to all of them, like visiting all the National Parks, only sitting and drinking instead of hiking and sweating. :)
