Sure, the staging could be different for women. Or they could just wear something appropriate to how they know they'll be situated.
Or, radical thought, the standard setup for these kind of events could be something that enabled women to wear whatever perfectly acceptable clothing they felt like, so they wouldn't have to spend any more time considering the staging than the average man does.
(I've been listening to Caroline Criado Perez's book all day, and I'm slightly pissed off with everything!)
