Topshop's free personal shopping service is the ultimate lazy girl luxury. A style adviser, kitted out with the latest must-haves, will visit you in the privacy of your home, office or hotel room. If you like a bit of girly camaraderie, then you can always organise a Topshop party: as hostess, you'll be entitled to 20 per cent off (for further information, call 020 7323 0326).
