I posted a little while ago about walking through a busy store while in drab and actively watching to see who actually looked at me. Answer very few.
So today dressed to blend enfemme I did the same. In truth I'd have to say more people made eye contact but not that many more. Outside in the busy pedestrian area most people seemed oblivious to me. A few read me as we walked towards each other but the vast majority just didn't see me or if they did as I was dressed to blend saw something that walked like a female, dressed like a female, acted like a female so no need to look any further; subconscious said female.
I know this sort of thing has been posted before but it's worth emphasising. Don't dress like a hooker, dress for the time and place and being out and about soon becomes second nature.
