Most new brands like this eventually turn into a chav brand. Bench, G-Star, Lyle & Scott, Henleys, Jack Wills, Hollister, A&F, etc. I'm not aware of any that haven't tbh, which means if you want branded stuff, you're better sticking to clothing from brands like Armani, Versace, Prada, etc.
...which is probably why I never have money.
I think people are banding the word 'chav' around a bit too much in this thread.
For example let's look at Superdry. Yes some chavs may where it, but it's owned and worn by people in all walks of life, from kids right up to respectable tax paying people in their late forties.
I wouldn't say that's 'chavvy', it's just a brand that has become so over popular that it's not cool anymore.
Your suggestion of sticking to brands like Armani, Versace etc isn't much good either because what they sell the bulk of are diffusion lines, which are their cheaper heavily branded ranges. These aren't the expensive, well made and designed pieces from superior materials, they are made in sweatshops just like everything else. I've seen plenty of people in 'Armani Jeans' or t-shirts with big 'Amarni' on it, but it's just crass and that same person is highly unlikely to be spending money on actual proper high end Armani, which is made from quality materials but has a price tag to match.
Abercrombie frequently has ques during busy periods, but then they have one UK store and have tons of Europeans in there who go because they don't have one in their own country.
I personally like A&F clothes, though I prefer the stuff that isn't overly branded, like they do with say the t-shirts. The trouble is the store is such a nightmare; it's interesting the first time, but after that all you want to do is buy clothes. Problem is you can barely see them properly because of the low light. The 'models/sales assistants' may be pretty... but have you actually ever tried asking one for help?
"Errr... sorry Sir, I'll have to ask somebody else, I'm not trained to stand on the ladder to get a pair of jeans down."
Don't even get me started on the ques for the changing rooms either...!
I got quite annoyed once that the 'model' who was responsible for checking doors wasn't really paying attention and was just joking around with another one of them. He totally missed that two of the changing rooms had been free for a good ten minutes while there was a que of about 15 people waiting to use them. The stupid thing is that they then also just open a door when they aren't sure whether somebody is in a room or not... would make more sense if they just had something simple to put on the door to say it's occupied.
Oh and the music is like something out of a gay nightclub.
I don't believe they have sales though, as they don't need to have them. If it's busy at the moment, it's most likely because people are assuming they have one.
