White ( or much better slightly off-white ) suit, is a full summer suit
So I wear it with colorful open collared shirts ( solid colors though, not hawaian type, even that could also work ) and canvas oxfords, very light brown shoes, or spectators.
It is a suit I only wear to partys and informal gatherings though, more like a costume or an exageration of the summer spirit.
Never for business. unless you are a health care profesional.
