(Do americans call aprons 'jumpers'? I'm so confused. One of these anyway:

Ours are exactly the same, just without the white writing at the top.)
I've wanted to post this topic for months, but I'd been trying to get a photograph, but I've not gotten an opportunity at all, and it doesn't look like I'm ever going to get one as the only aprons we have are at work and I'm not allowed to be on my phone there, let alone faffing around trying to get a full body shot.
I pass 90% of the time in real life to people that I don't know, but only twice have I managed to pass at work. Obviously I know that some of that is due to be living in the same village for 16 years, and in the pub I work in for 15, so a lot of people know me/know of me and notice that I look like my mother/father, and that they only have a "daughter". Not everyone is from the area though, and not every knows me. Part of it is probably due to wait(ress)ing being a predominantly female job as well.
But only one passing experience in 2 years of work? There's got to be more to it than that, and the only thing I can think of is that I wear an apron there, which is tied around my hips. Anyone have the same problem, or know how to mask the effect at all? The knot comes undone if I tie it any looser, and I've tried wearing black, white and blue shirts (I'm only allowed to wear white these days, but the new landlord doesn't dare say anything to me if I wear black because he knows he can't afford to lose me

) all to no avail.
