I have been blending some girl jeans, shoes and tops for a couple of years with nary a sideways glance. I have made an art form of imperceptible makeup. Don't have long nails or any hair for that matter.
I did get a bra strap noticed one day when I was getting gas and paying cash. I could tell the guy behind me saw the strap by the look on his face when I turned around, plus he was still looking at my shoulder. I didn't remember that morning that I was going to need gas and wore a bra under my tshirt like I usually do on my way to work. Only to take it off under the shirt a couple of blocks before my shop. He didn't say a word to me, but a that could have been because I was about 6 inches taller and over 100lbs heavier than he was and I am sure he didn't want to risk it.
