I am 5’6 and about 185. I ordered myself a large and it was way too boxy and not flattering at all (pardon my workout clothes that I tried this on over quickly). The arms and shoulder area, however, fit great and I think if I ordered a medium it would not fit! Sigh. I loved the color, it was beautiful! It came a little wrinkled but nothing an iron couldn’t fix. I returned it same day.
