Model Um Sang Mi posts a series of photos on her Facebook, "This dress is too small, and keeps falling down"
She promised fans to lose weight and become slim like Girls' Generation members which was met by oppositions, reports Kpop Insider.
Her fans commented, "Don't loose weight, you are great the way it is now" and "It's the fault of the dress, not you."
She made headlines last year by winning the Miss Maxim June event.
