And whilst we are on the subject of leather… The Leather Biker Jacket has proved not a trend item but a style staple. Skin up and be brave enough to mix it with a pinstripe suit but wear only the waistcoat and trousers. The two very different provenances work a curiously effective magic. If you stretched to a Balmain example from last season you don’t need to read this. That was a forever piece. Immaculate. But there is still hope. Check out the goods from Burberry to Sandro, The Kooples to Portobello Market on a Friday especially where one vendor has several examples dating from the 1960s in indispensible black, red, blue and many other hues. £3,000 will set you off in Paris catwalk style. Vintage from about £100 may suit a few more budgets.
