Arlo Weiner, who's made headlines for his impeccable self-styling at the age of eight, is back with fashion tips for spring. First and most importantly, the son of “Mad Men” creator Matt Weiner warns against using warm weather as an excuse to be sloppy. “I like being fancy,” Weiner says. “A seersucker suit is great in summer.” Shorts? Definitely not. “You can wear shorts if you have to but only if it’s really really broiling hot. I only wear shorts if I’m going on vacation to a hot place like Palm Springs.” Weiner also suggests his zebra-print newsboy cap and white button-down shirts as ways to keep cool.
