They seem to run a little small. I ordered med, which is what I normally wear. They seem to fit just a little snug through the bust area. I ordered a large for comparison, waiting for it to come in. I'm a little concerned the large will make me look like I am wearing a tent, we'll see when it comes in. If large looks better, I will be returning the meds I ordered & order everything in large, hopefully they will still be in stock.
