Not every US Open look can be a hit. A handful of ambitious designs this year fell short. (AP)

Whether baking in that blinding sun or basking under those late-night lights in Queens, the stars collide in New York for the 50th time to determine the US Open champions. As style points go, some obvious and more nuanced hits and misses present themselves. We've already covered the style successes of this year's tournament. Now, here are the relative eyesores at this season's Slam finale:

FAULTS

Dressed in Adidas, Dominic Thiem's gray-meets-red getup has induced yawns, though his tennis itself has drawn jaw-drops aplenty.

Hear this out. Yes, Serena Williams, Nike and Virgil Abloh created a ballyhooed collection with a nod to her love of dance and so on.

It's obviously a frock of many flourishes. But the dresses, replete with tutus, are ripe for twirling and yet short on sensibility. The single-shoulder visual trick doesn't match her skin tone, distractingly so, and the sum of all things seems more like a figure-skating outfit, though not in a good way. Setting the skirting against that jacket (a leather-esque holdover from her past New York warm-up gear) has not helped the sartorial situation; that piece, unnecessary in this New York heat, simply looks cheap.

Ready for another Serena-Abloh collab? Absolutely. Gagging over this particular combination? Not quite. Case in point: It could be the Louis Vuitton leader's signature "LOGO" treatment or Nike's trademark swoosh prominent at her clavicle, but it shouldn't be both. Make a choice. Just do it.

Nike and Maria Sharapova deliver a double fault here with a dress that can't seem to decide what its personality is. The result is simply underwhelming, which is startling from one of the game's premier fashionistas, one who has so many glorious NYC fashion moments on and off court.

John Millman, in Lotto, resembled a white-boarding session in which all the ideas tossed up for discussion got killed. It almost looked like a Rorschach test that developed into nothing.

Lacoste's polo for Novak Djokovic doesn't appear to know what it's to be. In the end, it's a bit of a crock.

One doesn't have to be American to rock a white-stars-on-navy-blue print, but on Karolina Pliskova, the Fila design has something of an undesirable childish effect.

That's a wrap—not the DVF dress, mind you, but the finale—of Grand Slam style in 2018. See you in Melbourne for another subjective style-centric scrum.
