Since when do the four coco hats ever were for men?
Also, there's a shoe on pillow hat and a pharaoh hat (all @ hallowed hex hat shop)

There's a pink hat and some other hats which may be for women at the swamptown pet shop

These are some of the female hats I spotted throughout the past couple of hat updates.
Point in short: female heads are being made but not too often. If anything, pretend to go with that they said about helmets being unisex and buy the ones you like
