Halloween for one night only? Forget it! At Anya Hindmarch, it's a week long event. Come 25 October, the fun-loving handbag designer will be hosting a week long Trick or Treat extravaganza at all stores and online, lasting until Friday 31 October. It works like this: customers will be invited to pick a sweet from Anya Hindwitch's Trick or Treat bag (no purchase necessary). Those who pull out a treat may win an Anya Hindmarch bag, clutch or purse from the autumn/winter 2008 collection; but for those who pull a trick, a funny forfeit must be carried out. Sinister stickers and bags of spooky sweets - jelly brains, skullcrushers and lucky bones - will be on offer to tempt both children and parents alike. Go to anyahindmarch.com to find your nearest spooky happening.
