Couple exchanges outfits on wedding day -- because bride thinks gown will make her look fat

Guests at a wedding in Nanchong, Sichuan province were surprised when the couple walked out wearing each other's outfits.

Photos on Shanghaiist show the groom in a flowing wedding gown and the bride in a smart-looking tuxedo.

The couple had met in 2011, when Ou Qian was a young and slim lady who weighed just slightly over 40kg.

Having packed on some pounds over the years, she was self-conscious about putting on a wedding gown and wanted her husband, Wu Shuai, to wear one instead.

Although Wu was initially reluctant, he eventually gave in to his bride. He said, "Sometimes you just have to put yourself in her shoes. It's the key to a happy marriage."
