Not a fan of Tattersall. It's seen a lot round these parts. Usually blue/red under a well worn fisherman's jumper with baggy cords and Cornish pasty shoes or green wellies.

I could see it working if you sharpened up everything else around it. Lose the country colours pallette. Navy trousers and knitted tie? Black loafers or longwings?

I think I'd end up changing the shirt just before I left the house though.
