I personally don't think there is a reason for sexy costumes anymore. Back in the old days, comics were basically soft core porn. You had characters like Wonder Woman with her low key bondage fetish. Then as you get further in the ages, the costumes get smaller and the tits get bigger.

Fast forward to now. You can see porn on any internet connected device any time of day. There's no need for soft core porn anymore when you have hard core whatever you want.

By arguing to keep overly sexy costumes you're basically trying to argue that we should keep jerking off to Victorias Secret catalogs instead of far superior internet porn.

Sorry for the Cho. It's the best example I had at short notice.
