Rory McIlroy did his best Arnold Palmer impression in Round 1 at Bay Hill, at least with his choice of outfit.

The defending champion paid tribute to Palmer with a navy polo and yellowish pants, a look made famous by "The King."

Most notably, Palmer's iconic umbrella emblem took the place of Rory's usual Nike logo.

He also sported these beautiful shoes:

McIlroy wasn't the only one to show support for the late golf legend, as Rickie Fowler and Bryson DeChambeau were also decked out with umbrellas.

Fowler's bag was also covered in Arnie's logo.

And perhaps the most meaningful tribute, Palmer's grandson, Sam Saunders, dawned these colorful shoes with his grandfather's face on them.
