WATCH 14-year-old's prom dress design for big sister will blow you away

A teen created her sister's showstopping prom dress from scratch, and the results are amazing.

Courtney Lewis, 14, made her design come to life as a gift for big sis Mikayla Lewis, 18, to wear on the day of her high school formal in Maryland. The floor-length sequin gown, complete with back embellishments and a train, was revealed on April 26, mom Crystal Lewis told "Good Morning America."

"It was a perfect gift -- a dress created by your sister, custom made for you," said Lewis, a mom of four girls. "I'm especially proud of [Courtney] because she was really swamped at school...and instead of resting all weekend she was working on the dress."
