My experience with inappropriate touching because of the costume I’m wearing has pretty much entirely been women. My costume wasn’t sexual or revealing at all either - people just decided to it looked pleasing to touch and did so without asking. Including one person repeatedly passing behind me to touch my costume at my butt (and I don’t think she was trying to sexually harass me: she was just really short)

Not saying its representative of the the wider behavior or even equivalent to similar behavior when done by men. Ultimately, I mostly just found it an interesting experience, but never felt threatened by any of the inappropriate behaviors, which makes a huge difference ime.
