Organisers claim Thriftstock 2013 will be the largest jumble London has ever seen. It's a mighty claim – though one that's amply backed up by some twenty tonnes of thrift. Arm yourself with a medium sized bag (£10) or a large carrier (£20) and pile in as much secondhand clothing from the '70s to the '90s as you like. If you're hoping to find that perfect cosy knit or coat, you best get your game face on: the jumble won't be sorted, so brace for the odd elbow and 'accidental' shove as you rifle through. We're sure the complimentary bar on Sunday will make up for the bruising.
