To be honest I think if it wasn't for their food section they'd be going the way of BHS. Their clothes are overpriced, poor quality and designed for pensioners - well at least the mens are. No young people shop there.
I think the problem with clothes retailers in general is that everyone is used to buying things as "disposable fashion" (Primark, H&M) or only buying when there's a sale on. My wardrobe is stuffed with everything from general high street brands to designer labels but I haven't paid full price for an item of clothing in years.
