Something Dorothy Perkins is really good at is making handbags in lots and lots of different colours. Their stud button despatch bag is a simple, easy to wear design, but the fact that it's available in no less than six different colours, it suddenly starts to seem a little more interesting. I think the purple and teal bags pictured above would be perfect for autumn, but if also comes in a rather more glamorous gold, a bright, fuschia pink and classic gunmetal and caramel. The price is either £15 or £18 depending on which colour you choose (and no, I have no idea why different colours are different prices either...)
