When I said fashionable, i was actually thinking of the scans of other issues with Vicky Vale (in a work appropriate yet modern suit) and Talia (in a halter top with shirred details). Also loved the way he drew Catwoman's goggles in one of the other covers (where she was skulking on the floor). Lord knows I hate those ugly goggles with a passion, but the way Guillem drew them -- large and looking like Jackie O/Audrey Hepburn sunglasses, very nice and classy.
In this particular frame, Ivy looks naked and all we see of Harley is her leg on heels (which i'm neutral about). Not much fashion here.
