I've learned quite a bit in a few years of shopping.
My hair is over 3 feet long. If it's down, people will remember me. I tend to put it in a folded over ponytail, a bun, a wrapped up braid, or just under a head wrap or hat so no one sees much of it.
I have giant tattoos on my back. I forgot and wore a tank to an oil change express... several people commented on the work. 0_o I learned real quick to not do that. I also have them on my feet and wrist. I make sure my shoes are closed up and my watch is on my wrist so people do not take notice.
I also have piercing holes in my face and ears from being a weird one in college. Still a weird one, but in a different manner these days. I tend to cover those with tiny concealer dots if I think it may pose an issue. Rarely ever do people notice but one day someone [rudely and loudly] exclaimed OH MY GOD YOU HAVE HAD YOUR LIP PIERCED--- TWICE!!!! 0_o I tried to tuck my hair over my ears so they didn't see the dozen holes in each one. Sheesh. I cocked my eye brow at her and said "the key word is had there, anyway, what can you tell me about..."
I'm tall(er) at 5'8"ish so nothing I can really do about that. I have had a few people comment when they realize that they're not towering over me because they're usually the tall woman. My banker once upon a time was 6' and she immediately noticed I was a taller woman. Don't think I was outted though.
Oooh I literally stuck out like a sore thumb once. I dislocated my thumb and it was still fresh but couldn't pass up a $250 bonus car shop (I used the bonus money into a set of front tires). When I checked in, the guy said something along the lines of holy @#$@#$ and had half the garage coming to investigate my hand.
I was sketching at a car dealership once and a fellow took notice and kept coming over to investigate the artwork. I don't sketch anymore and usually work puzzles. Or flip through boring magazines. I don't know if I'd call that standing out but it brought unwanted attention. I was also wire wrapping with copper once and a similar thing happened so I stopped doing that too. I get antsy/bored when I gotta sit for 3 hours with daytime television going. I haven't had TV service in over a decade and we don't do much TV other than say, 7-9PM tops. I don't wanna watch Days or General Hospital or even CNN.
Someone noticed animal hair on my hoody. Apparently the kitties decided it was a good spot for a nap. I dunno about standing out there either but I felt weird when someone casually mentioned I must have pets and started a convo up with me about animals that lasted longer than I wanted to talk about them.
You'll learn and sometimes still stand out.
And even with tattoos, holes, and all that -- business clothes and proper attire take away most of any standing out. Now, if I'm going to do a Spencers shop, I'll straight up put in a lip ring, half dozen hoops, wear my funkiest metal band shirt, and roll with it
but most days you'll find me hanging out with a long blonde braid, a pants suit, dressy sneakers (I have heel spurs 0_o), minimal makeup, a Timex watch, my wedding band, and a single piece of gold jewelry around my neck.
Also, I'm a very weird eater so I try to hide out in a corner where I can't be spotted messing with me food. Example: I don't like to eat the bottom bun of a burger so I toss it, straighten things up, and flip it over like a half a bagel. I also remake every wrap I get because I like it rolled a certain way. I don't want to be spotted as the weird person playing with their food
