When Katherine Mayfair (played by Dana Delaney) returned to Wisteria Lane (with a dark past), she was the perfect foil for Bree as the two battled for homemaker supremacy and eventually became partners in a catering business. Katherine’s ultimate rival, however, would be Susan Mayer (Teri Hatcher) as she battled for – and won – the affections of Susan’s ex, Mike Delfino (James Denton). When Mike and Susan reconciled, Katherine began to unravel – and turned her attention to seducing everyone’s favorite plumber before finding a new love and relocating to Paris. In fact, the sultry ensemble pictured above was worn on-screen by Katherine in a bid to tempt Mike in the sixth-season episode “Don’t Walk on the Grass” – and it’s now available to the highest bidder on the Desperate Housewives page at VIP Fan Auctions.
