They're a classic and should never go out of fashion, I've just had my original replaced by hubby which I'd had for years. I sold it on Ebay and we bought the exact same one but it's scratch free !
I think they are bit dated now and quite common and lots of high street shops copying them - wright and teague is better but that is just my opinion if you like it wear it who cares if is in fashion there are just lots of them about now
