I always come up with shit but can't think of any atm
Hey, you're in Seattle, right? Isn't there some masquerade event going on on the 31st or something? You can Chadvince some thirsting foid to attend, you can show her the mask you'll be wearing (make sure it stands out) and just keep it on for most of the night as you string her along. After the new year count down you take it off and reveal you catfished the slut.
And if you can (optional), wear boots or lifts to appear taller, wear like a coat or clothes that can cover anything that could expose you. Shit, since it's a masquerade, gloves wouldn't seem weird either. But foids aren't good at catching hints anyway, they're easily fooled, especially if she thinks it's Chad, and foids love alcohol so the whore would prolly be catching drinks at the bar till her senses get even further warped. And since she thinks you're Chad, you can convince her to buy YOU drinks lol.
