1. Kenneth Jay Lane earrings
For the capital’s deadline surfers with deep pockets, Net-a-Porter is a godsend. Its London Premier service costs extra (check your postcode online) but you can order up to 10am on Christmas Eve for items to be delivered later in the day – elsewhere in the UK, Sunday morning is your cut-off. If Alexander McQueen frocks are out of your price range, these sparkly studs look luxurious but even with delivery, won’t break the £50 barrier.
