Will a princess party dress dry faster hanging inside, by a window, over an A/C vent or outside, in the direct sun with ungodly humidity?

I'd go with the inside, drier air.

Over the A/C vent, in view of a sunny window if possible. The A/C is pumping out dehumidified air.

Outside or over the AC vent. *g* I'd go for the AC vent if its on continuous flow, IMO. I've dried sneakers out fast that way.

We usually just hang 'em on the towel rack in the bathtub...

In front of the a/c vent... and if there's still residual dampness as the time draws nigh? hang it on the shower curtain rod and blow dry it.
