IN A SPIN: London footwear label Charlotte Olympia is in a giving mood in the run up to the holidays. Come Dec. 1, the label will debut an online slot-machine game called “Spin to Win” on its Web site, charlotteolympia.com. When customers sign up to the site, they will be able to play the slot machine in virtual reality, aiming to match up images of Charlotte Olympia shoes and handbags. Those who bring up three matching styles will win a prize, which will include designs from Charlotte Olympia’s Christmas collection, such as the label’s glitter Kitty Flats, Holly Pandora clutch bag and Jingle Bell Dolly platforms. Visitors to the site will be able to win prizes every hour of every day from Dec. 1 through Dec. 12. “During a busy holiday season with a competitive retail landscape…brands are focused on new-customer acquisition. We wanted to ensure that this word-of-mouth campaign brings new customers to Charlotte Olympia,” said Bonnie Takhar, president of Charlotte Olympia. Charlotte Dellal, the brand’s founder and designer, will be counting down to the game’s launch on her Instagram, @charlotte_olympia, and on the label’s Web site.
