The experts at sexy advertising, Victoria's Secret could really attract attention by playing off of Snapchat's reputation of supposedly being used for sexting. Send a snap with hot lingerie model and suggestive language, "hey, gorgeous, you look smokin' hot, but you'd look even hotter in this lace panty. 2 for 1 today only! (keyword-gorgeous)" Use keyword or open at register. Would be enjoyed by girls and guys. If they get even sexier, and create some controversy...even better. More publicity!
