Do's: The short-sleeve button-down shirt is to guys’ summer style as the wedge heel is to us ladies—an easy way to dress up one’s look while remaining sneakily comfortable. Trade up from your standard T-shirt and wait for the ladies to flock.
Don'ts: Tank tops. Sorry bros, I don’t care how much work you put into your delts this winter. This is not the beach, and you are not a lifeguard. (The exception to this rule? Basketball jerseys, but only those of players who’ve been retired at least five years.)
