I considered the more recent catwoman incarnation but really determined that's not fitting for a five year old. We're going old school, Julie Newmar style catwoman. I've got the boots, the black pants, the black shirt, the black ears but I need the gold belt and most importantly the gold necklace to pull this off.
I couldn't find a lion button or charm so I cut the head off a toy lion.
Perfect.
I found this necklace on clearance at Claire's for $5. I removed the gem from the center medallion.
Glued on the lion's face.
A coat of metallic gold spray paint.
Hanging out to dry.
And I do think this catwoman necklace will do the trick. Princess Fierce is happy, well, she's kinda fierce here.
