This week I launched my annual off-season WTA fashion retrospections with an overview of Serena Williams' Nike 2015 dresses and now I'm eager to show you all the Adidas by Stella McCartney outfits that made Garbine Muguruza comfortable during her milestone season. Notice that in my previous yearly overviews the honor was always given to Caroline Wozniacki, while now I feel it's time to move on to the world No.3 Spaniard.

Muguruza opened the season in Sydney, wearing the previous year's Adidas Fall Adizero Dress in color vivid berry, most famously worn by Ana Ivanovic.
