The pictured garment is a men's T-shirt by Lacoste (Stretch Piqué range with striped collar).

The key visual and material features of this shirt are:

Design & colour: The shirt is in a deep wine red / dark burgundy (Dark Burgundy / Bordeaux). The crew neck is accented by a contrasting, striped rib-knit collar (dark blue with white-yellow or light blue decorative stripes).

Brand logo: The characteristic Lacoste crocodile is located on the left chest. On this specific model, its colour is discreetly coordinated with the garment (embroidered tonally).

Material structure: The top is made from fine mini-piqué knit, a variant of the classic, slightly textured polo fabric, which gives it an elegant appearance.

Cut & fit: Short-sleeved T-shirt in a Regular Fit (straight, classic cut) with a slightly elastic material content (Stretch) for greater freedom of movement.

Condition: Excellent, like new.
