With Labor Day looming, fashionistas everywhere are clamoring to get their best all-white looks in before the fashion police start demanding they return the shade to their closets—at least, we assume that’s how that rule works.

Anyway, enter: Olivia Dunne.

At the US Open this week, the retired gymnast and three-time SI Swimsuit model—who graced the front page as one of four cover models for this year’s issue—proved that a monochromatic white ensemble may be simple, but it’s still the top choice for sultry late summer styling.

Walking the blue carpet for the tennis event, the model sported a fitted two-piece set that expertly toed the line between full-on corpcore chic and laidback business casual.

A fitted halter-style vest with neutral button details down the front made for the perfect top, while she opted for flowy, wide-legged bottoms in a matching cream hue. Later in the evening, she donned a white pullover sweater tied across her shoulders for an elevated-but-effortless final look. She then accessorized with a couple of sporty touches for the tournament, including a pair of classic red Chuck Taylors and a navy US Open-branded baseball hat.

Dunne left her signature blonde hair down and straight so it sat neatly on her shoulders. Meanwhile, her summertime-friendly glam included dewy skin, pink cheeks and glossy lips. Throughout the star-studded sporting event, the model was spotted enjoying herself while dancing, drinking and blowing kisses to the camera.

But this exceptional ensemble wasn’t Dunne’s only show-stopping ensemble for the US Open—oh no. The LSU alum also shared a completely separate look on her TikTok account earlier this week, which couldn’t have been more different than her all-white corpcore moment. Still, there’s no denying it was equally on-trend.

In the brief clip, Dunne was seen sitting on the sidelines while sipping a drink in a tube top-style maxi dress crafted in a deep cocoa shade, which was positively covered in this year’s hottest pattern: polka dots. The frills of fabric featured throughout the garment, paired with the absolutely adorable matching headband, added a layer of 1950s-style glamour that elevated the outfit from mere audience member to star of the show.

For the TikTok itself, the retired gymnast collaborated with content creator Ava Grace to recreate a sweet tennis-related scene from Diary of a Wimpy Kid 3 (an absolute classic, as we all know—and no, this isn’t sarcasm. Those films are iconic). Dunne lip-synced along as the sound said, “30 love.” The camera then cut to Grace, who responded coyly with, “Whatever you say...love.”

All in all, it’s safe to say Dunne had a silly and stylish time at the US Open!
