Casual and generous, but there is no need to be too solemn. There is no uniform standard for the color of clothes and trousers, but generally speaking, the choice of color should not give people a gloomy feeling, nor should it be too bright to make them look like a roast chicken.

I recommend several colors.

Coat: beige, linen, dark blue, brown, rust red.

Pants: dark blue, black with red threads, dark brown, jeans, beige (never wear pure white)
