The 2017 US Open: Most stylish accessories

Earlier on Monday, Baseline delivered the best of the best on-court styles in the Fashion Aces of the 2017 US Open. Now it's time to dive a little deeper. Here's an array of accessories that provide singular style points:

Diego Schwartzman, Fila – Best Hat

Ventilated, vintage precision. It's so simple and splendid.

Jo-Wilfred Tsonga and Garbine Muguruza, Pharrell for Adidas – Best Visor and Headband

These two champs know how to get their style games on with gusto.

Style is subjective, to be sure. Many enjoyed Garbine Muguruza's Adidas visor blessed by Pharrell,​ and the collection on the whole,​  while one of the most pleasant commentators out there needled it mid-match against Petra Kvitova:

Rajeev Ram, Mizuno – Best Shoes

It's always good to see that it's not just the Top 10 singles elite who get personalized touches. Bright blue-and-yellow for the win:

Tennys Sandgren – Best Facial Hair

The Best Name in Tennis deserves a spot on this roster. Yea, the Sandman knows exactly what he's doing.

Federer, Nike – Best Warmup

Sleek and slenderizing, it's the piping that sets this jacket apart.

Madison Keys, Nike – Best Practice Tee

Keys is making much figurative noise in this season-ending Slam, and not just late at night versus Elina Vesnina. By all means, "Wake Up" – just not too early after a 1:46 a.m. finish.

Tomas Berdych – Best Practice Kit

We didn't see much of it (here's to you, Alexandr Dolgopolov), but T-Berd's practice attire made a great connection between shirt and socks/shoes.
