I ended up having to reorder this as the UPS guy threw my package over my fence and dogs ate it. Whenever the second one arrived I used my brothers acct. to order (he doesn't have dogs), I tried it on and it was wayyyyy too small. I used the little measuring chart and everything and just to give myself a little room I ordered a XX. It was far too snug to be decently  worn in my office. Great quality though, maybe I'll order a 4x?!
