This really looked good on my fiancé, who is 6'1 and has a long torso and broad chest and shoulders. It was looser in the midsection. I got him an XL.

Essential Black for the Musician
Color: Black, Size: Medium, Color: Black, Size: Medium
This button-down shirt looks genuinely nice, and my son being in the jazz band means he always needs sharp, dark attire, so this will be great. It presents a clean, classic look that fits right into a professional setting.
I truly believe this represents a great value when you consider the quality of the material for a button-down shirt. It’s a solid staple piece that you won't regret stocking in your wardrobe for his band commitments.
