Thank you so much for this comment, it really put a smile on my face! Attention to detail is one of the most important things to me in costuming, and I really get excited when people notice them. Plus, for all of my Becky 'looks', there is meaning behind each detail
. The bird skulls(and the feathers, on my regular brown costume) obviously represent crows, but the reason why is because she was unafraid to stand up to Scarecrow(in the comic New Year's Evil). She's "brave becky", she's the bird that's not afraid to sit on the Scarecrow's shoulder(and possibly even peck at him sometimes
And the needles are, of course, protection/"weaponry" essentially for her. My version is a villainess, Mistress of Fear, but she's still a disabled character and Scarecrow himself is not a beefcakey character that can protect them both physically from Batman(or any other threat). So she needs a small arsenal of Fear in order to feel ready for whatever possible threats may come their way during their schemes.
Sorry for the long reply, I went off on a tangent! Thank you again for the kind words
