No Small Plans Productions will host a Season Seven Premiere Party at the theater, 2646 N. Milwaukee Ave., that will feature cocktails, desserts and lots and lots of "groovy" attire.
"People do get pretty serious about the dressing up, and now it's heading into the very groovy era," said event organizer Kristen Kaza.
The year will be 1969 as the seventh and final season premiere — a time when bell bottoms and flower power reigned.
Kaza said attendees don't have to be pinned down to 1969, though.
"I think that there'll be people who do come and are excited about being very period-specific, but I think it's more about celebrating the style and flair of the 'Mad Men' era and the spirit of the show and the 1960s," Kaza said. "But I do have a period-specific outfit myself that's very 1969, and I can't wait to wear it!"
Prizes will be awarded for best outfits and include items from Comet Vintage in Pilsen and free tickets to the Logan Theatre.
Tickets will be $25 at the door, though last year's event sold out beforehand.
