Runs very large!
I'm not sure i recommend this shirt but i did purchase the plum yesterday. i'm always always a m and had to size down to an xs on this one. that's how large it was! even the xs had plenty of room; i'm 5'6 145 lbs 36b for reference. the material look like it will stretch out even further but i got it anyway. it was on sale plus 25% off and for that price i can use it for casual days on the weekends. it's comfortable on and loved the lace detail.
