Dude Looks Like a Lady
Wolfwood's scream of terror awoke the others.
"Oww, my head. Whazzamatter?" a hungover Vash moaned.
"You! Me! LOOK!" Wolfwood said, dragging Vash to the mirror. The two stared in disbelieving horror at their reflections. Both wore badly applied makeup. Vash was clad in a flowered sundress with a matching hair ribbon, Wolfwood in a skirt ensemble.
"What's going on?" asked Milly. They simply gaped at her.
"HOW-?" Wolfwood began.
"WHAT-?" asked Vash.
"Oh, don't you remember?" Meryl replied. "Last night you wanted to be 'pretty'. You tossed your normal clothes out the window when we finished. You were really drunk."
Yeah. I think the prompt for this one was gender bending somehow. I'd imagine Wolfwood's is wearing Meryl's outfit, and Vash one of Millie's dresses. Honestly, though I think I like the idea of smeared makeup the best.
