Walking into Unknwn is like strolling into the pages of some mind-blowingly hip fashion magazine like Nylon Guys. With a mix of establishment-approved, up-and-coming fashion labels (Band of Outsiders, 3.1 Phillip Lim, A.P.C.) and street-wear brands (Warriors of Radness, Crooks & Castles, Stussy), the Aventura Mall outpost is a must-visit for any guy. This is designer wear at designer prices, but they aren't into the stratosphere (check out some sleek A.P.C. jeans for $158 or a 10 Deep varsity jacket for $154). There's stuff for the ladies too, but Unknwn stocks the kind of menswear that until now has been suspiciously hard to find in Miami. And oh yeah, it's owned by some guy you might have heard of: LeBron James. He's six-foot-eight, plays basketball, is kind of a big deal. The Heat forward teamed with a group of friends, including longtime pal Frankie Walker, to open the boutique, but the inventory is the real star here. Even if the owners were unknown, we'd still stop here to stock up our closet.
