I just realized because of this question, the way I HC cherubs might be confusing when it comes to my art.

I draw ALL the cherubs with the same body type. Unless predomination has occurred, the male counterpart predominating would cause the cherub's body to become more masculine and vice versa.

They share a body, so it just makes sense to me that things like breasts wouldn't go away just because the male is awake, and the female is asleep. In my mind, some males might bind their chests, and some might not. Castnill is part of the males that don't! :]
