Leah Still shows off flower girl look for dad Devon Still's wedding

Five-year-old cancer survivor Leah Still will be the flower girl in her dad's wedding, and she just revealed one of her cute looks for the big day.

Houston Texans defensive tackle Devon Still is marrying fiancee Asha Joyce on May 13 at the New York Public Library, ABC News reports. Because STill and Joyce are The Knot's 2016 Dream Wedding couple, the magazine's fans voted on every aspect of the wedding.

The dress Leah will wear to walk down the aisle is being kept secret until the wedding, but she modeled her look for the reception on Good Morning America Tuesday.

The sparkly pink dress, which Leah helped design, is meant to make her feel like a princess -- a strong princess, designer Hayley Paige told GMA.

"She wanted something that was really playful and girly but also really strong and fearless," Paige said. "I think when she puts that dress on she's going to feel like Elsa [from Frozen]."

Leah's supporters have been following her journey since she was diagnosed with stage 4 neuroblastoma in 2014. Lately, though, Still has gotten to share good news. In January, he posted a message celebrating one year since Leah had gone into remission.

Good Morning America will host a "Wide World of Weddings" live-stream of 100 weddings in 24 hours starting Thursday at 8 a.m. ET.

The Walt Disney Company is the parent company of ABC and this station.
