Good afternoon ladies and gents!
I can recommend one particular shop on the Cowley Road in Oxford that sells a variety of vintage clothing at excellent prices. Called Reign, it caters for men and women and sells a variety of shoes, hats, waistcoats, leather jackets, dresses, eveningwear, shirts, ties, belts...you name it! I picked up a gorgeous waistcoat from there for £14 and the girl is very friendly.
