How to dress as the Robert Downey Jr. Sherlock? ?

How do I dress as the RBJ Sherlock? The dress clothes I have right now include black and brown pants. Grey and black vest, white, black, pinkish and a red plaid shirt. A pinkish blazer, and an assortment of tie colors. So what should I wear. What else do I need to buy and what can I use that I have? Thanks!
