Question: Is there any logical explanation for the lavish costumes used by the characters in the Shumacher films? For example, Poison Ivy always wears lavish outfits (ludicrous tights and heels and multi-thousand-dollar-looking outfits and robes); or Two-Face from "Forever" and his split suits). I know it is for the style, but is there any realistic explanation as to how this could happen?

Answer: You answered your own question. "Realistic". This is a movie trying to look like a comic book. Comic outfits are drawn on, no seams, no underwear/bras, etc. So live action costumes are just going to look odd.
