She covered the main cast of characters, including Enchantress...
...the unicorn-loving Captain Boomerang...
...and of course, Harley Quinn.
Phi Phi told BuzzFeed she was inspired after falling in love with the film: "The casting was perfect, plus the movie was nonstop action, colour, and perfectly tied in all DC movies."
Each costume took a day to make, but Killer Croc was the hardest to create because Phi Phi drew "every single scale".
The costumes are part of "365 Days of Drag", a daily series that Phi Phi created to challenge herself.
"It has been so hard to keep up with all the days, but I have done it...and ready for it to end so I can sleep!"
