Lifestyle Style Model Katrina Scott on Walking 'SI Swim' Runway Despite 'Swelling, Hormones' from IVF Cycle The Tone It Up co-founder and mom of one hopes to inspire other women to "keep your head high and your heart open" during difficult times By Kaitlyn Frey Kaitlyn Frey Instagram Twitter Assistant Style & Beauty Editor, PEOPLE People Editorial Guidelines Published on July 16, 2021 01:50 PM Share Tweet Pin Email When Tone It Up co-founder Katrina Scott hit the Sports Illustrated Swimsuit catwalk last weekend, her trip down the runway was more than just another modeling gig for the 37-year-old. It was a moment to help inspire others trying to conceive. Scott, a fitness entrepreneur and mom to 2-year-old daughter Isabelle, was in the midst of IVF treatments when she got the call asking to join the crew of women participating in SI Swim's runway show during Miami Swim Week. "With IVF, I had to have a surgery called hysteroscopy," Scott, who previously suffered two miscarriages and a chemical pregnancy, told TODAY Parents. "After that, they put you on high levels of estrogen." Describing the hormone therapy as an "emotional whirlwind," Scott admitted that she didn't feel close to bikini-ready when it was time for the fashion show — but that didn't stop her from turning down the opportunity.

Jason Koerner/Getty Scott strutted down the catwalk in various swimsuits including a cutout one-piece, high-rise thong bikini and patterned two-piece. She looked back on the experience in a heartfelt Instagram post, saying how proud she felt to "represent all the women out there who feel like it's too late for them." "IT'S NEVER TOO LATE! 💫 I hope to represent all the moms… you are remarkable and so strong. I hope to represent the women yearning to grow their family… who may have experienced loss (my 3 angels), and all my IVF warriors who are holding onto every month praying for their family," Scott said. "I hope to represent the women who have had the hardest year of their life… and show that there's still light and to keep your head high and your heart open."

And I hope to rep the small town girls (NH baby!). Most of all… I hope to represent YOU. I hope I made you feel proud walking this runway!" John Parra/Getty Also on the runway at the event were 57-year-old model Kathy Jacobs, Jasmine Sanders (a.k.a. Golden Barbie), who attended with her boyfriend, trainer Anthony Rhoades, Natalie Mariduena (who became famous as YouTuber David Dobrik's assistant), and 13 Swim Search hopefuls selected from SI Swim's annual open casting call.
