Many retailers may be cutting back on openings. But Teen Vogue has decided now is the time to experiment with opening stores. The magazine opened a store, called the Teen Vogue Haute Spot, in the Mall at Short Hills in New Jersey. The store, however, doesn't hawk merchandise. Instead, it is meant to be a spot where teens can hang out, decompress, try on clothes and get exposed to marketers. The pop-up shop opened Nov. 28 and will remain at the mall through Dec. 26.
