You didn’t think you could stay in shorts all summer, did you? A noble goal, but with some semblance of a social scene back in semi-full swing, the season demands a slightly dressier alternative to the T-shirt and slides combination. A summer suit is a necessity for any man—something handsome, smart and light for all of those formal dinners, back-to-the-office parties and destination weddings. Houndstooth and wool, while attractive options, aren't going to cut it in ninety-degree heat, so opt for lighter fabrics like seersucker, linen, cotton or tropical wool (wool's loose-woven, breezier cousin).

Speaking of looser, summer formalwear should be all about comfort. A fitted, slim-cut suit is a tried and true method, but don't be afraid to try a relaxed, boxier fit, either. Just remember, supple doesn't have to mean sloppy. Ditch winter colors for neutrals like beige or a pleasant gray, or try something bolder, like a pastel, to really lean into an elevated summer look.

This season's best summer suits embrace all the tenets of dressing in 2021. Fit is king, comfort is queen, and a carefully crafted elegance is expectation, not transcendence. How you wear them, too, should vibe with the suiting rules of 2021, not 1991 (no more stuffy shirts and bad ties). There are all sorts of options for pulling off seasonal suits; for a beach bash, don't be afraid to try a knit polo or patterned camp collar shirt, as opposed to the same old boring button-up. Even if you prefer the classic look, make sure to accessorize with the right pocket square, watch and jewelry. Browse our picks below for the best summer suits of the season.
