Bermuda shorts
Casual with style
Bermuda shorts had the British military shorts as a model.
They should be as well-tailored as a pair of suit trousers, ending about 2.5 cm above the knee, and formally worn with knee socks, loafers, blazer, shirt, and tie.
At least if you want to dress well for a reception in Bermuda.
Informally, they look great with a casual linen shirt, Italian moccasins, and as always, a well-worn Panama hat.
