Every now and then there is a product that is so good, it sells out almost immediately. This often happens with sought after designer items–think of Bottega Veneta's square sandals or their must-have bag – but it doesn't happen that much in the world of the street. So, if a street name sells out quickly, you know it's something special.
This is exactly what happened to Topshop's Black Keyhole Midi Dress. We first noticed the LBD on Camille Charriere in December, though unfortunately the dress didn't last long. The combination of the effortless midi length and the irresistible £ 25 price tag was clear enough to add customers to the basket without any thought.
