Great jacket!
Size: 4X-Large, Color: Dark Blue
Nice jacket for warmer weather, very comfortable, fit me well. I'm a big guy and wear a 54 regular in tailored sport coats. The 4XL fit nearly identical to a 54 regular. Adds some class to a nice outfit without making it formal, which is exactly what I was looking for.

Comfortable & Right Fit
Size: X-Large, Color: Light Grey, Size: X-Large, Color: Light Grey
Light Grey, XL *Item returned before use due to color change* Quality every day blazer. Good material didn't feel cheap or come with lose threads. When buttoned the blazer laid flat, I had room in chest and stomach but didn't seem baggy. Shoulders fit across without pinching or buckling around pads. Arm length didn't hang past wrist when arms were at my side and also didn't pull too high when raising. My measurements: More of a solid, muscular build but still very average. 6' 215# Chest 44" (circumference) Shoulders 20" (length taken from back) Waist: 38" (circumference) Arms: 26" (length taken down outside of arm)

Fit is decent. Sleeve are to long for me but I often have that issue. Was VERY wrinkled when it arrived. Had to be pressed before I could wear it out.
