If Leah Still's flower girl dress ends up looking a lot like a pink version of Elsa's gown from Disney's Frozen, don't be surprised.
It's her favorite movie, Elsa is her favorite character and well, she just loves pink.
"I want my dress to look like this," the spunky five-year-old told PEOPLE as she held up a sketch at a recent consultation with designer Hayley Paige at her New York City headquarters.
"Lots and lots of glitter!" she giggles, then adds with a shrug. "I'm a glitter girl."
Not only is her father, Devon Still, getting his dream wedding, Leah is getting to design her dream flower girl dress with Paige.
Her father couldn't be happier.
"I knew pink was going to be involved," he says with a smile. "She loves princess stuff."
It's hard to tell that the spunky, self-described "girly-girl" sitting in a boutique Manhattan bridal shop designing her own tiny, sparkling hot-pink flower girl frock was battling life-threatening stage 4 neuroblastoma cancer just weeks ago – but doting dad Devon Still says that's just his daughter's personality, resilient and consistently positive.
"She's just had the best attitude of fight and then move forward with life," Devon, 26, tells PEOPLE of his daughter. "And look where we are now. I'm getting married to my love and Leah gets to be a part of this wedding. We overcame tragedy and are becoming a family. It's like a fairy tale."
Nearly two years ago, the recently signed Houston Texans defensive tackle and his fiancé Asha Joyce put their wedding plans on hold after Leah was diagnosed with the deadly disease. Doctors gave her a 50-50 chance of survival.
Her diagnosis made headlines across the world in September 2014 after the Cincinnati Bengals cut Devon from their roster but offered him a position on the practice squad so he could keep his health insurance to help pay for Leah's cancer treatments.
Devon publically documented his daughter's two-year battle on social media, and officially announced that she "beat cancer," in January.
The couple, who will be married in spring 2016, was selected by TheKnot.com, as the recipients of this year's Dream Wedding.
