Adidas has the future pin-up boy of tennis on its books in Stefanos Tsitsipas but it has some work to do in ensuring his play does the talking.
It was impossible to ignore the Greek star's shorts during his 6-4 6-2 7-5 defeat against Daniil Medvedev on Friday night that sent the red-hot Russian into a final against Novak Djokovic.
Everything was in place as Tsitsipas entered Rod Laver Arena. His magnificent mane was secured by a stylish headband, his socks were pulled high and his tennis ball coloured shirt fit the occasion.
But it was a muggy 30C in Melbourne and with an at time impassable backline presence in Medvedev across the net, it quickly became sweaty work for the 22-year-old.
That's to be expected at this, or any level, of professional sport. But apparently Adidas' apparel developers hadn't accounted for it.
