Originally ordered a 1X and it fit like a drape! I’m usually an XL. (which wasn’t available) and I was unsure about sizing down but i HAD to have this so I chose a L and returned the 1X AND IT FIT JUST FINE. although an XL would’ve been easier on my heavy boobs I’m still satisfied and can’t wait to wear it! PURCHASE YOUR NORMAL SIZE OR SIZE DOWN DO NOT SIZE UP!
