While Andre Agassi and Steffi Graf have historically won Halloween as the best couple's costume, and Laura Robson regularly dominates for best makeup, Eugenie Bouchard always wins for greatest effort. She hasn't yet dressed up for Halloween 2019, but there's no doubt she'll come up with something to top all of these past looks.

The Canadian usually commits to multiple costumes, and proudly shares them for the world to see. Here's a look at her best ones:

Though she hasn't won on court in a while (she's on a 13-match losing streak since February), she always wins at Halloween. The world No. 22o's season isn't over yet as she's scheduled to play a WTA 125K Series in Houston in two weeks.
