I am now in love with the whole tweeds and cloaks look now. I think this look is beautiful! A way to create a Sherlock Holmes look you will need a great eye for colors and lots of tweeds, browns, tans, grays, and a great template.
Just put what you love in here! Doesn't have to match! What I think would work would be the colors that are on there or the totally opposite color. Basic colors, neons, patels, and anything that is appeling to your eye! Just think like an artist and have fun with it! :)
