A high school senior attended her prom like a true star, wearing a one-of-a-kind original dress, all thanks to her younger sister.

Like most seniors, Mikayla Lewis, 18, was prepared for the grueling search to find the perfect prom dress. But with some prodding, 14-year-old Courtney Lewis was able to convince her older sister to let her design and construct the dress.

And the art school student didn’t disappoint! Courtney designed a stunning dress for her older sister and made Mikayla’s big night even more special and memorable.

My 14 year old daughter tells people that she wants to design doll clothes when she grows up. People look at her funny because it seems like an odd career choice. But I know my child, she'll design doll clothes and she's going to be great at it. She told us she was going to create her sisters prom dress and I looked at her funny! That's a major event. I even saved money to the side, for just in case. And then I decided to have faith in her ability and used the money for something else. The video highlights the journey. Have faith in your ability! Don't let anyone dictate the outcome of your journey and destiny because it sounds odd to them.

“The dress came out more beautiful than I could have imagined,” the sisters’ mother, Crystal Lewis, told Yahoo! News. “We had about 25 people at our house on prom night, and when Mikayla walked up the steps the family screamed in excitement. We think her date was even taken aback.”

Courtney and Mikayla began working on the design of the dress back in November.

Mikayla and Crystal were both initially hesitant—Crystal even admitted saving up money for a dress “just in case.”

But they saw Courtney’s potential after seeing her early sketches. Courtney was then mentored by her cousin Syreeta as she began constructing the dress.

Though Syreeta owns her own fashion line, Courtney did the work all on her own and completed the dress by April 26th, despite being hospitalized twice due to complications with type 1 diabetes.

Courtney has a vast interest in the arts and is currently in art school. According to her mother, the 14-year-old plans to have a career designing clothes for dolls.

“Courtney has always been interested in the arts. She attended a performing arts middle school as a theater major. She’s done make up for a megachurch theater production,” Crystal explained.

“So, it was no surprise that Courtney would ask to take on the task of making her sister’s dress. I was worried at first because of the lack of experience in dressmaking. Courtney had only made a few pillows and skirts prior to the dress,” she added.

After receiving so much praise for her first design, Courtney may need to consider transitioning from doll clothes to haute couture.

“When I saw the dress on Mikayla, I was a bit emotional,” the young designer’s mother said. “I’ve always had confidence in Courtney’s talent, but to see it on my oldest almost brought me to tears.”
