It's Go Big or Go Home When It Comes to Kentucky Derby Style

The model looked lovely in a cream-colored midi skirt and collared shirt, topping off her outfit with a large, bow-like headband.

Sarah opted for some standout headgear as well, pairing her floral printed dress with a veiled, feathered fascinator.

He may be playing Casey Jones in Teenage Mutant Ninja Turtles 2, but this time around, Stephen left his creepy hockey mask and stick at home. Still, while his navy suit and patterned tie are sharp, we can't stop staring at his shoes: just look at those blue laces!

Josh Groban kept it kind of casual, skipping the tie and leaving his white shirt slightly unbuttoned under his light blue suit.

We don't know which piece we love more: Kendra's floppy hat or those high-waisted black pants. So chic!

It's like we've traveled back in time. We're totally getting Audrey Hepburn — or at the very least, Amal Clooney — vibes from Vanessa with those gloves and vintage hat.

Vanessa's husband, Nick Lachey, looked ready for the Spring and Summer seasons, trading in a basic black suit for a lighter khaki one.

Everything's coming up roses — at least for Johnny Weir, who paired his printed outfit with a colorful and fun rose hat.

Ne-Yo also joined in on the statement hat trend, completing his all-white look with an orange fedora that matched his tie.

The night before the big event, Sarah Hyland showed up at the Fillies & Stallions Derby Eve Party in a pair of short ruffled shorts, a V-neck top, and a some black booties.

Lindsay was also in attendance, wearing a low-cut printed dress and some colorful strappy sandals.

Kendra looked very elegant at the preparty in a long, black cap-sleeved gown, which had some lighter details around the neckline.
