Grand Slam style calls for elevating one's sartorial game. While there were those who hit winners on court at the onset of New York Fashion Week, others made no headway on the concrete runway in Queens. Here are this year's US Open fashion faults. May they fare better in 2020.

Bedecked in Ellesse, Johanna Konta won big with the dress she wore whilst beating Karolina Pliskova. This, her Other Look, seemed an afterthought, with an underarm chevron print short on inspiration. The player may be British, but with this, the brand handed her far too much white outside of Wimbledon. It ended up looking blank.

Elina Svitolina, Belinda Bencic, and more Nike stars donned a top seemingly fit for a new parent. As our own Ed McGrogan posited on Twitter, this kit "looks like it has baby formula spilled on it."

Admit it: You've been wowed by Roger Federer's ensembles and accessories over the years, but you're terrifically bored with what Uniqlo has put him in, for the most part, since he signed on with the brand for a reported 10-year, $300 million deal. In black and white, this henley did not serve to change that.

It took a lot to make Sloane Stephens look dowdy, but Nike just did it. Her Air Jordan Aqua collaboration was great, but the rest of her look fell short.

Novak Djokovic's Lacoste kit, namely that polo, were to convey the movements of water. But the shape of water here was a snooze, not a breeze—and it rendered him blending in, from top to bottom, with the blue court. Simply not a kit befitting a 16-time major singles winner. They of the crocodile did much better by Hyeon Chung, Denis Kudla and Kristie Ahn, et al.

This was purple gone wrong: Elise Mertens's Lotto dress looked like a bad wallpaper brought to life, replete with accidental peeled-banana print.

Cashing out on their 2019 major showings, Angelique Kerber and other Adidas sponsorees met untimely and/or unsightly ends. The mesh-back top was fun. The ran-out-of-fluorescent-paint skirting looked unfinished—kind of like the business they came to New York to do.

Oh for the days when Feliciano Lopez looked princely in Ellesse. No more. Hydrogen gave the southpaw a look for the bargain bin perched between Hot Topic and Ed Hardy.

Chase these fashion faults with the event's wardrobe aces. And like what you see here? Think there's a glaring omission? Sound off on Twitter to @Tennis or at @jonscott9.

Here's to another major year in the on-court style game.
