Seems like Topshop has a constant wandering eye when it comes to making dresses “their own.” When compared to Catherine Malandrino’s Draped Silk Jersey dress, the similarities are obvious, but are only limited to the silhouette and assymetry. Topshop went for a knitted version and nixed the ruching that Malandrino’s number has:

Topshop’s is quite a steal at $90, while Malandrino’s is $495. But the question still remains. Would you go with the price, or with quality?
