top end off the peg oxfords in a slim cut?

[Bananafish]

Could anyone recommend some trad oxfords in a slim cut that I could pick up without paying bespoke prices? Would love to find something of vintage '60s BB, Arrow or Enro quality and weight. Those vintage shirts drape like parachuts on me, and I cannot seem to find a contempo truly slim cut that matches the quality of these old oxfords which is disappointing. Any help would be appreciated.
