Quality shirt
Color: Angel Falls, Size: XX-Large
Great quality fabric , style, and fit. My husband loves the fabric and colors. Ordered his normal xl but too tight across his stomach so returned and sized up , and fits much better. Even sizing up the shoulders hang nicely . He likes so much ordered two colors, both great.

Nice shirt for the price
Color: White, Size: Large
Good quality shirt, especially for the price. Drapes nicely, almost a painterly feel with the fabric. Works across the wardrobe spectrum, pairing well with slacks in a business setting or with chinos for a more casual look.
