The individual in the image is wearing a white button-up shirt. The shirt has a classic design with a pointed collar and is long-sleeved. The material of the shirt appears to be light and slightly textured, suggesting it might be made of cotton or a similar fabric. The shirt has a left breast pocket and it is worn tucked into the pants. The overall look is clean, simple, and elegant, emphasizing a minimalist style. The person's hair is pulled back, which complements the neat appearance of the outfit.

A person is wearing a white, point-collared button-up shirt with a slightly textured cotton fabric, tucked into beige, slim-fitting trousers with a subtle texture, and paired with brown leather belt and taupe loafers with a minimalist design.

For a formal afternoon gathering, I suggest pairing the outfit with a navy blue, slim-fitting blazer made from a wool blend fabric. The subtle texture of the trousers will blend seamlessly with the textured blend of the blazer.
