Major championships are the most important weeks in golf, and if you watched last week's Open Championship at Royal Birkdale, it wasn't hard to see why. 

The world-class talent and relatively benign conditions resulted in a big wave of low scores and a memorable Sunday showdown between two of the top names in the game: Jordan Spieth and Matt Kuchar.

Majors attract a lot more eyeballs than your standard PGA Tour event, so apparel sponsors often pull out all the stops to have their players looking sharp. This year's Open was no exception — in fact, a couple of especially bold style choices caught fire on social media, generating the most buzz about men's golf fashion we've seen in ages.

Below, check out some of the most memorable fashion statements from the Open Championship.

Justin Thomas and his classic cardigan and tie combo were the talk of Royal Birkdale on Thursday. The 24-year-old shot an opening round 67.

Jason Day had his share of highlights in Southport, but his Air Jordan golf shoes attracted far more attention than his play.
