The wine retails for about $29 and features a label with a silk-screened image of the starlet.
"We've been selling the wines since they came out," said Hi-Time owner Tobin James. "People love them. People have always loved Marilyn Monroe, so when the merlot came out, it developed quite a following."
The event will also feature a Marilyn Monroe impersonator and free tastings.
"It's an easy-to-drink wine," said Donna Holder, Marilyn Wines co-owner. "It's mellow, velvety, soft, luscious — generally the same descriptions people use for Marilyn Monroe."
The 2009 merlot is ready to drink, but should keep for a decade.
While the event is hosted by Thirsty Girl, "thirsty boys" are welcome to join the party, too, said Thirsty Girl owner Leslie Sbrocco.
Her company is all about celebrating a passion for food, travel, libations and life — something that Marilyn Monroe embodied, Sbrocco said.
"I'd like to consider that Marilyn was a Thirsty Girl," she said. "I'm sure she was. Thirsty Girl is about living life to the fullest and enjoying it."
