Type of Shirt: Mandarin collar shirt (also commonly called a Chinese neck or band collar shirt).

Color: The shirt is a light, solid blue color, often described as aqua, light blue, or sky blue.

Collar: It features a mandarin or band collar, which is a short, stand-up collar without a traditional fold-over lapel. The top button of the shirt appears to be unbuttoned.

Placket: The shirt has a central button-down placket.

Sleeves: The sleeves are long, but the man in the photo has rolled them up to about the three-quarter or elbow length. The cuffs are visible at the end of the rolled sleeves.

Branding: A circular Tommy Hilfiger logo patch is prominently placed on the left side of the chest. The logo is the classic red, white, and blue, with the word "TOMMY HILFIGER" written in a circle around the central "H" design.

Fit: The shirt appears to be a slim-fit or tailored-fit style, conforming to the man's body without being overly tight.

Fabric: Based on the way the fabric drapes, it is likely a cotton or a cotton blend, possibly a dobby or poplin weave, which gives it a slightly textured look.

Style and Look: This is a versatile casual shirt. Its light color and band collar give it a clean, modern, and slightly relaxed aesthetic. It is suitable for a smart-casual or everyday look.
