Voted one of the best luxury clothing stores in the world for good reason, Selfridges is the ultimate high-end department store.

Farfetch boomed during the pandemic, not least because their sustainable push and closer relationships with small and independent boutiques saw their pre-owned section become seriously elevated. It’s well worth a look if you’re after pre-owned high fashion, like Chanel bags and Cartier jewellery, for less. Equally, their new-season selection serves straight-off-the-catwalk pieces from the likes of Off White, Burberry and Prada.
