(Was £20) BRITISH ARMY PARADE/DRESS TROUSERS

This is a pair of British Army Dress Trousers, the red stripes doe have some moth bites to it and some to the trousers, all the buttons are in place, unsure of the period as I cant see any labels inside but my guess is the 50s, Approx. size is a 28' waist and a 29' inseam leg.
