I am pretty sure that this EleVen Brushstrokes NYC Inspire Dress is what Venus Williams will wear at the 2016 Australian Open. The Brushstrokes collection has been available for quite some time already at both Tennis Warehouse US and Tennis Warehouse Europe, while yesterday EleVen posted the below photo on Instagram, saying:
Spoiler Alert: this MAY be the style Venus is wearing on court at the Australian Open! Tune in to find out!
Although EleVen didn't confirm anything, I'm quite certain Venus will opt for this collection, as she will certainly not introduce another one and she will not wear old clothes either.
