Kendall Jenner & Gigi Hadid Attend U.S. Open Wearing White After Labor Day — PHOTOS

The supermodels are clinging to the last vestiges of summer style before the cold comes roaring in. Kendall Jenner and Gigi Hadid attended the U.S. Open in New York and the runway strutting pair did so in summer-y fashions. Jenner broke a formerly hard, fast fashion rule, wearing a white outfit after Labor Day. Meanwhile, Hadid donned a red bandana over her denim shirt, giving off a sexy and fun rebel cowgirl vibe.

Kendall, whose outfit was a bit fancier than Hadid's, rocked a fuzzy top that perfectly demonstrates how autumn-y white pieces can be. Hadid's layers — if you want consider her neck gear a layer — veered a bit towards the fall spectrum of dressing. Her bandana mimicked an infinity scarf and added such a blast of color to an otherwise basic top.

Hadid also used her new beau Joe Jonas as a pillow, leaning her beautiful, blonde head on his shoulder in some of the candid snaps. It was pretty darn precious.

But what was most refreshing about Jenner and Hadid was the joint "no makeup" makeup look that each boasted. Both were dewy, barefaced, and had their hair tossed back into loose and unfussy updos.

I love the cut of Kendall's sweater-like halter. Gigi was such an urban cowgirl.

I also applaud Kendall for wearing what looks like fuzzy and itchy material on such a scorching hot day in NYC.

Why so serious? The ladies kept their eyes on the action while all eyes were on them looking their casual summer best.

It's so refreshing to see the models fresh-faced and looking comfortable IRL and off the runway. Both ladies take loads of gorgeous pictures with full faces of makeup and while draped in couture. It's nice to see them let loose and let go while taking in some tennis.

Of course Gigi's BF Joe Jonas was looking casual and comfy in a graphic tee. They're each other's best accessory.
