Seems plenty of them in Manchester and Sheffield where I currently seem to be spending most of my time. My general observations are they tend to be estates kids or from the less glamorous area’s. It doesn’t seem to be a fashion that’s hitting the more middle class. I find it a very confusing mix of influences for a fashion, but it’s certainly got an anti-establishment draw for those disenfranchised teens. This generations ‘hoody’ I guess.
For the record I am all in favour of manbags, and I’m an active user. I think they can set off an outfit nicely, but maybe not as used above.
