Generally ignored or treated like a female, called maam. I do notice if people are looking at me but not sure if it is more than they would anyone else or not but i try to have a smile, be confident and do what I was doing, look at phone, browse, jut ignore it. Blending in is key, being in a skirt and heels at Home Depot is a bit unusual and lots of construction guys in there so I got a few looks lol. Being in jeans or leggings and a top in a mall is ignored.
I have been called sir a few times and they quickly apologize and correct themselves but it is a shot to the ego. I have gotten a few cat calls which are flattering and discomforting all at once.
I do tend to stay to safe places, hotel, restaurant, stores, and go out in short spurts not spend most of a day out running errands as I would like to some day.
