I have discovered a genius item of clothing – a jumper with a smart shirt collar built in. This with a pair of suit trouser looks alright to me, and I suppose the suit jacket will fit over the top.
We call that a 'shumper'. Similar variations are the 'shank top' and even the 'shardigan'. A chap at work even has a 'hocket' which is a leather jacket with a hoodie (hood and front 2 inches only) that zips in.
This sort of clothing is very popular with designers such as the ubiquitous 'matt alan'. It tends to be worn by middle aged men who can't grasp the basics of clothing and have been forced to dress themselves. Even having your partner/spouse shop for you is a step above shumpers.
TJ – copying and pasting sartorial advice from an American is as sensible as me asking you for a one word answer on the subject of 'roofing in the Edinburgh area'. You dress like someone else buys your clothes, then someone else decides what to wear, then someone else dresses you – all on separate continents, without any communication, colour perception and a delay in the postal system of several decades. Can you just get some scrubs? :D
