MARYVILLE (WATE) – A Maryville high schooler’s prom didn’t go quite like she expected after a wardrobe malfunction.

A friend posted a picture of the teen on Facebook saying that the girl cried in the bathroom because she was asked to wear the vice principal’s jacket over her dress because it was too revealing. The post said the teacher told her, “Us big girls gotta cover up.”

The post has gone viral with more than 11,000 shares and almost 40,000 likes, but may not tell the whole story.

The teen’s father told WATE 6 On Your Side that an alteration to her dress broke after this picture was taken, causing the dress to be much more revealing once she was at the prom. The picture in the post shows a piece of lace that was added to make the dress more conservative. The girl’s parents said that the lace broke off, which made the neckline several inches lower and wider than in the picture. That’s when a teacher asked her to wear a jacket.

WATE 6 On Your Side will not publish the photos of the teen in the dress after the alterations broke, at the request of her parents.

Sharon Anglim, a representative of Maryville City Schools, says there is no specific prom dress policy in place. No other girls at the event were called out for similar reasons.

Anglim added that the neither the girl nor her parents complained to the school district about the incident.

The photo has been shared on Facebook nearly 5,000 times.
