I love to see people out and about who've made a bit of an effort. I've been through a few different fashion phases in my life, including goth-lite and fifties vintage. I'm all about easy clothes at the moment (pregnant with young kids) but it makes me smile to see people with a strong "look", whatever it is. I concur with PPs that everyone judges in the sense of thinks something about someone based on how they look. Right now people probably think, "Poor her!" when they look at me!!
But I think your OP meant judge in the sense of disapprove. So here's what I really think. I really dislike those stretchy/gauged ear piercings as they make me feel a bit ill to look at them. Definitely have to consciously avert my eyes and think of something else. I disapprove of people going out in basically their underwear, which is what the teenagers around here are doing at the moment - girls in jeggings and a glorified bra, boys with their shirts off and pants hanging out. Makes me tut like an old lady.
And specifically for goths, some goths do use Christian symbolism really disrespectfully. Not just a goth problem, but rosaries, crucifix necklaces etc are common in that fashion scene. And #notallgoths - most see the religious symbols as neutral fashion accessories and obviously they're more to me than that, but I'm not too fussed about that. However, I have seen for example some really unpleasant goth t-shirts making fun of serious religious paintings and that definitely makes me think, "Well we're not going to get on, are we?"
But overall, it makes me happy to see someone who's put a bit of effort into their dress as I find it interesting to look at - whatever vibe they're going for.
