Very nice fit.
Color: Navy, Size: X-Large, Color: Navy, Size: X-Large
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.

A Good Casual Shirt
Color: Wine Red, Size: Large
This shirt is just what I was looking for. A relatively cheap, casual button down for summer outings, brunches, and dinner.
It fit well, but is a little slim around the waste so I would maybe size-up. I got a large and it feels more like a medium around the waste, but the length is good. The material is definitely cheap but cool enough for the summer, and more casual than some of my other button downs that I felt overdressed with.
For the price you really can't complain. You don't have to worry about ruining it, but it looks high quality than it is.

Comfortable Stretch Shirt with a Clean, Fitted Look for Everyday Wear
Color: Black, Size: Large
This short sleeve button-down shirt is made from a lightweight fabric with a soft texture and noticeable stretch, giving it a flexible and easy-to-wear construction. The material drapes cleanly and maintains a structured appearance during regular use.
The fit is tailored with a more defined cut through the chest and sleeves, creating a streamlined silhouette. The fabric holds its shape well and shows limited wrinkling compared to heavier woven materials, helping it maintain a neat appearance over time.
Stitching and construction appear solid, with consistent button alignment and secure seams throughout. The collar retains its structure after repeated wear, and the overall build quality remains stable after multiple uses and washes.
The fabric composition allows for a lighter overall feel, and the design works well across different styling combinations depending on the setting.
Overall, it is a well-constructed button-down shirt with a tailored fit, flexible fabric design, and consistent build quality suitable for regular use.
