From what i've seen, people here are still wearing alot of Polo, chinos, Lacoste, sperrys, wallabees and such. Alot of people are starting to jump on Burberry though, idk why. When I got my check shirt, I saw 2 other people with the same one, and like 10 people with either a check scarf or a knockoff.
Ugh, check is so obnoxious when not used as a subtle accent, and I've been noticing the comeback as well. A check button up might be alright if you wore it under a sweater, but I think it'd be over the top on its own. Check looks alright as the lining in my trench, but I prefer the lining in my Aquascutum one, as there are far fewer people that recognise the pattern, and that means I don't have to talk to shitty people fawning over check like dirty chavs.
