I use the esl40 since 2 weeks at work with jeans.
I walk and talk with costumers.
If you look very closely and know what you are looking for, you can see it i guess.
Not ‘looking for it’ i don’t see how people would see it.
Hm. If they see it they wouldn’t say anything i guess.
Gonna ask a female friend of mine if she notices anything when she looks at me from top to bottom.
