Fit advise: Currently I flop between a 1X and XL. I tried and kept the 1X in this one. It is on the fitted side, but I actually love it. It's great for layering under a button up shirt or cardigan without adding bulk. Plus the straps are wide enough to over a real bra strap and I don't have armpit gapping.
