I'm not that familiar with Adidas, only what I've received in the past two boxes. I think their sizing is maybe a little on the smaller side although the slides seem to be bigger. Maybe because they are slides and the design of it. They are a little big on me too but I'm going to keep them. I'm afraid that sizing down would be too small.Is anyone very familiar with Adidas products? I am wondering how much difference there is between the different sizes of tank and slides. The tank is a bit snug in the bust and the slides are a large (but not falling off large) on me. Not sure whether to try to get different sizes or if they would then be too small. (For some reason Adidas is not carried in stores locally though I am not in a rural area. I wasn't able to find anything 'Adidas' in four five shops I tried so I gave up and just guessed--hard because I don't usually wear work out gear.) Thanks!
