Model Mara Martin turned heads at the Sports Illustrated swimsuit fashion show Sunday.

The 30-year-old hit the runway in a bikini while breastfeeding her 5-month-old daughter, Aria.

Martin, who’s from Monroe, Michigan, was one of the 16 finalists — which include a former maid and a security guard — chosen by the magazine’s open casting call at Miami Swim Week.

Before the show, Martin uploaded an Instagram with her adorable smiling tot.

“The face you make when your mom makes it to the final 16 of the @si_swimsuit Swim Search,” she writes in the caption. “Im so so so thankful for the entire team at Sports Illustrated for picking me.”

Post-catwalk, fans flooded Martin’s Instagram with supportive comments.

“This is so powerful,” writes Haley Kalil, who won this year’s SI Swimsuit Model search and also walked in the fashion show.

Some social media users were less into it, commenting that it seemed “over-glorifying” of breastfeeding and “unnecessary.” But in general, the response has been positive.

“That was one of the most beautiful things I have ever seen,” writes one Instagram user.
