Finding a decent vintage-style knitted tie is hard enough, but finding one made of silk and for a reasonable price is even harder. Not if you go to Debenhams it isn’t.
The department store has an exclusive (and low-priced) Duffer of St George range called St George by Duffer. And in that range are these pure woven silk knitted ties. Not just these available – there are other stripes combos as well as a plain grey.
The only downside might be the width, but at just £18 each, it might be something you can live with.
