Convention may have it that the groom doesn't see the bride's getup until she walks down the aisle. (Or sometime very close to the actual exchanging of I Do's). For one Chinese couple, the groom didn't just see his wife-to-be's gown before the main event: He put it on and wore it.Ou Qian and Wu Shuai, a couple in the Sichuan city of Nanchong, swapped wedding-day outfits because Ou didn't feel confident in her gown. She suggested trading outfits with her fiancé so that she'd be more comfortable for the occasion. A Facebook post from news channel CCTV describing the couple's wedding day switch-up from over the weekend (shown below) has since gone viral.“Sometimes you just have to put yourself in her shoes,” Wu told a local publication. “It’s the key to a happy marriage.”Bridesmaid/groomsmen outfit swaps have transpired before, like the one between this pair of cousins. But a bride and groom trading looks, and for a pretty thoughtful reason, sort of takes the cake, doesn't it?
