This is now my favorite go to shirt. Easy to wear and looks good with jeans or slacks. Washes well - I hang to dry so have had no shrinkage. One pattern I have worn multiple times and it shows no signs of wear. Not unusual to have someone ask me where I got it. The MEDIUMS I have fit but emphasize the breast area. The LARGES fit looser giving a more casual look. ( 5'4 -150lb -36D ) I would say they run true to size. I usually wear a size L with occasional size M. Silky fabric is lightweight but not thin.
