Query: Nice Tank But Runs Small

I bought three of these tanks recently. They are high quality and wash well (though I have avoided putting them in the dryer), and the colors are very pretty. I recommend ordering up one to two sizes, because they run small. In my case, I found I had to get an XXLarge for a comfortable, although still fairly close, fit. I normally wear a medium/large (size 10-12).
