Birds Of Prey: 10 References And Easter Eggs You May Have Missed
7. The Harlequin Corset
Towards the end of the film, Harley uncovers a chest of her old things - grenades, her old Suicide Squad outfit, and most crucially, her old corset.
Though Harley most notably wore a corset in her New 52 reimagining, the corset is also notably reminiscent of her original full body harlequin outfit, which makes it not only decidedly striking, but also undeniably cool.
Cooler yet, it's revealed that this corset is bulletproof, which is a genius decision as it explains how Harley actually managed to survive her tumultuous and dangerous early days as a supervillain, instead of just being shot down by Gotham's police.
That said, it's actually cooler that Harley chooses not to wear it, as it can be seen to show her development in the film into a character who has progressed past her roots - and that's pretty great to see.
