Relaxed Fit Cotton Button-Up Shirt

Nice fabric weight, not too sheer but lightweight. Bought in size Large which is charted as a 12-14, but this has a wide-waisted body and even larger hip, and fit more like an XL (16). The shoulder/arm is dropped which gives more roominess but somehow the neck is small and pulls back. I tried tucking it in and the neck pulls at the back. This was just a weird fit on me and it was too long. I might need a Medium in this style. I like the Polo Pony logo embroidered on the cuff but of course it disappears once you roll them up) but the buttons are unbranded.
