We bet you've had that trusty ol' flannel plaid shirt for ages, ever since your tween self decided that emo-core was the absolute height of fashion. Your past self wasn't completely wrong, however much you shudder at those Multiply-era snaps—Bea Marin is out here styling your staple checks cool and current.
All you gotta do is update, update, update. Layer chic, understated basics (a black turtleneck and A-line denim mini, in Bea's case) beneath, then get trendy up top with, say, a logo-brandishing bucket hat and thigh-high boots.
And yes, if you were wondering, we do believe in never throwing certain things away. Who knows, late '00s punk just might make a comeback!
