Last December, when Bandra-based sisters Sana, 30, and Alfiya Khan, 25, a dentist and a graphic designer respectively, decided to clean out their closets, they were left staring at a pile of clothes that they didn't know what to do with.

They were useless to NGOs due to their fancy cuts and designs, so they reached out to friends and decided to host a small get-together-cum-shopping session. Soon, they realised that many of their friends in the space-stricken city were facing the same hoarding problem. And so, they started a donation drive, and started calling themselves the Bombay Closet Cleanse. This Sunday, they are going to host the third edition of the thrift store in Versova.
