I am a big fan of the androgynous look which has been around for many years, may i add. Girls dressed like boys or just borrowing from boys. The tie around the neck is a big statement, but consider an understatement, like adding a tie pin.
For something more original, head down to vintage markets like Greenwich on a Wednesday/Thursday. you’ll be able to clip one or 2 for a few quid, I’m talking £2 – £5! best bit is, you can haggle…yippee
