casual white linen shirt and trousers set — button-down shirt, long sleeve, collared, wide leg trousers, elastic waist trousers

A man is wearing a crisp white linen long-sleeve button-down shirt with a relaxed fit, paired with matching white linen wide-leg trousers. The shirt is unbuttoned at the top, and the sleeves are rolled up, giving a casual, summery look. He is standing on a boat with a scenic background of a lake and buildings.
