Sorry, guess I was imagining you taking some artistic liberties with the idea (Portal 2).

Maybe--

Hazard Liquid melting clothing

Ruby inadvertently using portals to look up Puri's skirt

"Against glass" fun, but the glass is the hard light bridge/wall

Ruby's jumpsuit getting fizzled in the Emancipation Grid

Puri sassing back at GLaDOS, much to Ruby's chagrin

Puri making the obligatory White Gel innuendo

Puri accidentally zapping Ruby's clothes with a laser

Stuff like that I guess :P
