My best memories were with my late partner, when we'd dress-up to a theme, as many couples do. They're all favorites, but here's one we did:
He was Confederate Colonel Beauregard Pickett Frontage (frone-tahge), and I was his "lovely & curvaceous" niece Magnolia. We had authentic theatre costumes from Minneapolis sent to us, mine an 1860s ball gown with a huge 5-hoop skirt, gloves, fan, period jewelry, blond sausage curls wig, the whole deal.
We practiced the most outrageous, stereotypical Deep South accents for a couple of weeks, along with little routines we'd do. It's not enough in my mind to just dress up, and then simply stand there & pose - you've gotta do something with your costume, make it work, come alive, if possible fit the surroundings.
We went to a party at a gay nightclub. As planned we split up, and I started flirting with the men at the bar, coy behind my fluttering fan. Then the Colonel would storm up, and bellow in his heavy accent:
"Magnolia! You forget yourself!"
"But Uncle Beauregard, sugah, I was jess making acquaintances with these heah gentlemen folk. This is Mark, and..."
"Ah do not care to exchange pleasantries at a public bar, and neither do you, Madam. It is time we were goin'. And I shall attend to you latah, suh!" addressing his fury at some hapless guy at the bar.
Off we'd go, everyone laughing and some applauding, and then we'd perform another routine in some other part of the club. We had so much silly fun, not to mention all the free drinks I wrangled.
