IZOD mens Long Sleeve Button-down Oxford

I wear blue or white OCBDs every single day at college. This shirt is amazing. I bought 2 each of M and S to see which one fits me. I am 5'11" and 165lbs with a slim but muscular build. My go-to OCBD is the Lee Uniform Long-Sleeve Shirt, but I figured that it is time to test out the waters with other products a little bit.I wear a size Small in the Lee Uniform OCBD. The size Small in this shirt was a little too small across the chest (and I don't have a super-wide chest) and a bit too tight at the bottom; the size Medium fit very well in both places. The sleeves are a tiny bit long; there is a tiny bit of extra fabric in the rear shoulders/upper arms. However, it is very comfortable and feels like the quality is on point.
