Even though it has all those jewels and stuff. And even though it looks pretty feminine. It has to be male (A buck so to speak). It has antlers, there are nearly no female deer (I am not sure how to spell that kind of Deer ...Do?) anyways yes.
Because it has antlers it is most likely male. Kind of weird if you ask me :|
You thought he was female? Looks like someone wants to get gored by a forest prince.
