THE UPSIDE The 'Tennis Club' Limited Edition Collection is all about the golden era of tennis with nostalgic nuances and 70’s silhouettes — think V-necks, collars, pleats and the statement crochet fabric that adds undeniable vintage glamour. Aside from being very on-trend, this collection is also super functional, with moisture-wicking performance pieces that are made from cotton pique and 4-way stretch peached fabrics, so you can sport them on and off the court.
