Prom season wraps up this month, which means that clever high schoolers can begin planning next year’s extravagant “promposals” and parents can reclaim their wallets.

Not as eager for the festivities to end are Twin Cities area businesses, from tuxedo rental places to restaurants to blowout bars, which welcome the annual rite of passage that puts ka-ching in their spring.

“Prom brings us a lot of business when we would normally be slower,” said David Wohlforth, general manager of Chino Latino in the Uptown area of Minneapolis. While graduation parties help his numbers, it’s the “prom kids,” he said, who really boost the bottom line in May — and offer another perk. “Prom kids don’t stick around,” he said. “They come in, they have their dinner, and then, boom, they’re off.”

Let’s hope they at least leave a good tip. Here are a few prom-ising numbers:

$1.4 million: Prom bounty at Men’s Wearhouse stores throughout the region, said Joshua Iberg, manager at the Rosedale Center location.

10,000: The number of tuxedos the shops collectively rented.

300-400: Prom “clients” since April 30 at the Wow Bar in Edina and St. Paul, ranging from $35 blowouts to $70 updos.

200: Prom dresses sold at the David’s Bridal in Maple Grove, ranging in price from $150 to $300.

100: Corsages and boutonnieres ordered just last weekend from Flowerama in south Minneapolis. The average price was $20 and $10, respectively. □
