Sister style swap! Sarah Janer Nader sat down with ET to reveal she’d happily raid sister Brooks’ wardrobe, if only she could get past security.

“Brooks’ closet is full of maximalist pieces that I’d love to style, but she keeps that thing locked like Fort Knox,” the Love Thy Nader star joked.

While borrowing the Sports Illustrated model’s clothing is strictly off-limits, the sisters don’t hold back when it comes to sharing fashion advice.

“Brooks and I always run outfits by each other and are the harshest critics,” the Louisiana native dished.

One fashion moment that has their stamp of approval? The Avec Les Filles Return to Eden campaign collection, which stars the 23-year-old herself.

“Avec Les Filles does this really cool push and pull between softness and structure. … It feels really ethereal and thoughtful, like you’re stepping into a dreamy garden moment,” she explained.

“When we think of spring, we see it as a dreamlike chapter of calmness, imagination, and a return to something that feels quietly preserved,” the brand’s creative directors Sofia Wahlberg and Bradley Mounce shared in a press release.

The model’s current favorites include “flirty dresses, oversized dramatic trenches that are cool and easy to throw over, and cutesy denim sets that feel modern and intentional.”

This exact mix of romantic and relaxed pieces matches Nader’s mood-driven approach to style.

“You can dress them up or down, layer them, and make them feel totally your own. … Some days I want to be super feminine in a hot dress, and other days I lean baggier and more effortless.”

And fans can tune into the upcoming season of her family’s reality show for additional outfit inspiration.

“I’ve always loved experimenting with fashion and being on camera has made that even more fun. My style is always evolving, which you will see more of in season 2. … It’s all about confidence and having fun with it,” she noted.
