Ah, to be young again! Or, if you are model Teddy Quinlivan, to be young, have quite the breakout season, and catch the eye of photographer Phil Oh every time you step onto the sidewalk. A combination of doe-eyed innocence and too-cool attitude translated into angsty haute looks) and an off-duty energy that made Quinlivan a street style standout during London Fashion Week. She worked a grunge aesthetic, like a scrawled-on denim jacket on top of a fire engine red shirt, and added polished pieces like a curve-skimming plaid midi skirt; to tie it all together, so to speak, she turned to a recently revived punk staple, the grommeted belt. And Quinlivan has been championing other throwback favorites recently, too: Just a week ago during New York Fashion Week, she wore a particularly memorable vintage tee, featuring a bouffant-laden ’80s-era Bon Jovi, which she paired with skinny jeans and a cheeky Marc Jacobs kerchief tied around her neck. But the 21-year-old model knows how to execute elevated, precociously grown-up cool, too: Take the naval-diving, gold-threaded jacket that she wore as a belted dress with a half-bow-tied black scarf around her neck. We’ll be looking to see what wardrobe tricks Quinlivan has up her stylish sleeve during Milan, Paris, and beyond.
