It was a sad day for menswear when Glenn O’Brien, GQ’s resident Style Guy, announced he was leaving the magazine after 15 years. Throughout his time, O’Brien became the go-to guy for any and all men’s sartorial questions, ranging from whether we should match our socks with trousers or shoes, to proper interview attire, to what a dude should wear to prom. And although his advice was pretty sound, it became increasingly evident his suggestions were more suitable for the older generation. So when GQ was faced with the task of finding his replacement, it turned its eye to a younger guy: Mark Anthony Green.

Though he just penned his inaugural Style Guy column for the GQ September issue, Green has actually served as the magazine’s associate editor for the past few years. His experience working under menswear experts like GQ editor in chief Jim Nelson and Atlanta’s Sid Mashburn, make him more than qualified to dish out style advice in social-media age.

“I’m thrilled Mark Anthony Green is our new Style Guy, and look forward to the digital savvy he’ll bring to the role,” Nelson said in a press release. “We’ve seen a change in the way men interact with style, they’re becoming more daring, they want to try new things, and they want to try them now. Just ask our web team how popular searches like ‘can I wear a man bun,’ and ‘Ryan Gosling’s style’ have become (answer: VERY!). Mark Anthony is the guy to help you navigate all that, from the small lapel-pin-level details to the biggest investment piece queries, he’s got you covered.”

Green, aka MAG, was also included in our 2013 list of the most stylish men in media, along with O’Brien. So you know his taste level is on point.

You can check out his first Style Guy column at GQ’s website. Tomorrow, Green will host a live Twitter Q&A on @GQFashion from noon to 2 p.m. EST.
