The sleeveless shirt is the highlight of this US Open The two semi-finalists Alcaraz and Shelton are wearing a sleeveless shirt, making it the signature garment of the NY slam

The US Open tennis tournament has reached its final stages, with the men's tournament set for the Djokovic-Shelton and Alcaraz-Medvedev semifinals, while the women's tournament waits to discover the winner between Gauff and Sabalenka. The concrete at Flushing Meadows is considered the most unpredictable of the slams and even if the four finalists include the top three in the ATP rankings, the trend is confirmed by the semi-unknown Ben Shelton, a left-handed American who is thrilling the New York audience. Among the traditions of the US Open, apart from the great heat - also a problem in this edition - there is a special attention to uniforms, which over the years has led the tennis players to use very imaginative kits such as Serena Williams' leather one (2004) to Andre Agassi's neon yellow faux-denim one from 1990. In this edition, two of the four men's finalists have something in common in this respect, namely their choice of singlet, a style also followed by Tiafoe, who went out in the quarters. 

Speaking of generational talents, the new one may have been joined by Ben Shelton, a 20-year-old who reached the semifinals wearing a kit made by the Swiss brand On. Who knows if among the crazy kits in the history of the US Open in a few years' time, we will include the Nike singlet of these two young talents - along with Tiafoe's - or if it will start a trend followed by other players on the circuit. For now, it seems that Nike and On is a very specific choice, certainly designed for the heat, which has led to the interruption of some matches and some tennis players using ice bags to cool down. An improbable final between Alcaraz and Shelton could make the singlet the real star of this New York slam, between biceps in sight and an aesthetic legacy to start writing, one Spanish player after another.
