I think people are being purposefully obtuse as they don’t like it, of course it isn’t something like if you wear black you look depressed and some universal language. That’s not what making a statement or people making assumptions about you meqns.
Here is another example. Sitting in a coffee shop. People watching.
a woman walks in with low quality clothing, a cheap fake handbag, done in primark jeans, an anorak that would make hailey in corrie swoon, a short practical hair cut, no make up, and people make an assumption about that person, low income, dowdy, frumpy a bit dull, but likely approachable. Doesn’t mean it’s accurate, just that’s what it says.
a different woman walks in after her, she’s wearing cream wool trousers, a silk blouse, carries a clearly expansive leather handbag, has swishy rich coloured well kept hair, subtle make up, a subtle scent that smells expensive. People make a totally different assumption about her. Rich. Pampered. Rich husband or parents, or successful career. Stuck up. Likely not approachable.
another woman walks in, she’s wearing faded jeans, a leather biker jacket, an old band t shirt, doc martin boots, pink hair and heavy eyeliner. people make a very different assumption about her than the other two woman. Edgy, cool. Approachable, maybe, maybe not.
none of these assumptions maybe right but it is just made up examples of how people presenting themselves snd the view strangers may have of them based on their appearance. And what people mean by your clothed making a statement,
