Petticoat Lane Market
I love Petticoat Lane Market. It's not as trendy as Brick Lane or the Sunday Up Market but it does have it's charm and so much stuff! The street was first named Petticoat Lane as it sold petticoats and lace made by the French. During Victorian times the name was changed to Middlesex, but it's still known as Petticoat Lane. The market is like a massive jumble sale but it feels authentic.
I love this postcard of Petticoat Lane from Spitalfields Life - it's a great site that specializes in the area.
