The 3-Piece Uniform the Fashion Crowd Will Never Ditch

There are certain outfit formulas that just work—and will always work. As the fashion crowd continues to prove, a blazer, a unique top, and jeans are one of those go-to uniforms. Sure, it may seem somewhat basic and not inventive at this point, but there’s a reason the ensemble will continue to be a favorite. Even though it features just three pieces (minus the shoes), the outfit somehow masters that polished and sophisticated yet cool and laid-back vibe. Plus, if you opt for more current silhouettes in general (a checked oversize blazer, for example), the look will undoubtedly feel current every time.
