US tennis ace Heather Watson, 25, made a fine impression at the Battle of the Sexes premiere in London over the weekend with this pretty dark green satin gown. British No. 2, Watson, was at the 61st BFI Film Festival for the premiere of the American biographical sports film based on legendary women's tennis player Billie Jean King's 1973 showdown with US men's player Bobby Riggs.
Watson took to the red carpet with her tennis player boyfriend Lloyd Glasspool (below) and her showy-flowy dress -- especially its lengthy side slit -- had a lot of photographers rushing for a shot. In the run-up to the event, Watson, a former junior US Open and Wimbledon mixed doubles champion, had revealed on social media that she had to undergo a two-hour tanning process for her legs.
It seems to have worked like a dream, no?
