Wearing medals on civil 'livery' used to be the norm. The Corps of Commissionares even wear rank - bit like Beefeaters and Chelsea Pensioners.
A chauffeur is another although you rarely see that nowadays.
Police and fire service have medals and ex-servicemen wear theirs in those circumstances and that is uniform.
In the merchant navy they wear theirs. The EPO on the P&O cruise ships I have been on both had chest fulls. One had been on Resource and the other on a T42 in FI.
