Yves Saint Laurent is readying another mass mailing — but this time the signature envelopes will carry ounces of prevention. The house plans to celebrate Valentine’s Day by mailing 200,000 condoms to people in France. “Given the time in which we live, we thought it was a useful thing to do,” explained Christophe Girard, YSL’s secretary general. The love gloves will be sent in condom-sized packets bearing YSL’s new men’s wear ad, which features a clothed woman with a smiling, naked man in the background — and a tag line that reads “Yves Saint Laurent Dresses Men.”
