Classic and understated these two dresses seem to be born of the same cloth. But don’t be too quick to judge, subtle differences add to a large price gap. Both are knee length, black, cut in a classic silhouette and feature a tie waist. However, the Diane von Furstenberg Maylea shirt dress (Left, $325) is actually the designer’s famous jersey wrap with a pin tuck shirt and cuff inserts while the Viktor & Rolf version (Right, $1,640) is a silk crepe bib on a shift. Both are smart choices for the office, but the stiff collar and pin tucks assure the Diane von Furstenberg remain at work while the Viktor & Rolf is available for drinks. Both at Netaporter.com.
