Aryna Sabalenka has a signature that everyone recognizes. Not the one she leaves on cameras after a match. Or on autographs for fans. But the one she leaves in every match: her forehand.

So when Stella Artois invited Sabalenka to sign a clothing collection designed by Marina Ruy Barbosa, we didn’t offer her a pen. We offered her a racket.

Using her signature forehand, Sabalenka signed each piece the only way she could: by hitting tennis balls dipped in a gold pigment directly onto the fabrics, turning her most iconic shot into a one-of-a-kind fashion signature.
