Perhaps you've always wanted to travel to London - to steep yourself in its rich history, to shop at its most fashion-forward boutiques or to retreat into the cozy depths of its rustic pubs. Planning when to go may also have always been your biggest hurdle. While tourism and the prices hike in the summer, spring is just when the city starts to blossom. Go now, and step into a world that's at once edgy and sophisticated; antiquated and yet ceaselessly cosmopolitan. Make sure you dress right, too.

Fashion capitals
The U.S. has New York, France has Paris, and the U.K. has London. While Americans keep it comfortable and the French keep it relentlessly chic, Londoners choose from bright and sharp to country dapper. According to USA Today, it's only a short hop, skip and a jump from American to English style, with coordination being the added ingredient to comfort. All it requires, really, is a little embrace of the bold, from bright, cosmopolitan color to checked sport coats. 

The gentlemen of London
A look at some of GQ Britain's Most Stylish Men of the Week captures the zeitgeist. Actor Idris Elba, famous to American audiences as Stringer Bell in the HBO modern classic "The Wire," looks masterful in monochrome, donning an all-black suit and midnight dress shirt with a cool show stopper of a black tie. His is the purest demonstration that cut is just important to a style of suit as color. Lapo Elkann, a British entrepreneur, meanwhile, rocks a creamsicle orange velvet suit and tie against a white shirt and pocket square, topped with chocolate brown shoes. 

Pulling in that familiar British debonair look is the dashing Benedict Cumberbatch, star of BBC's "Sherlock Holmes" and the most recent Star Trek film. He keeps it simple with what appears to be a single-breasted wool tweed dark gray jacket, light gray dress pants and a blue-gray tie with a light white print to match the shirt. A brilliant touch of color comes in what appears to be a royal blue cardigan under the jacket. 

Style by the Thames
Sweaters, blazers and button-downs will be your passport into cool England wear. Every Englander embraces layering for those drafty evenings. Cardigans are the most stylish of these, though multihued marled sweaters or thick-woven donegal sweaters are warm and stylish choices. 

You can say it all with your sport coat. Plaid jackets are a leading trend at the moment. Checked plaid has an air of the country, while large-frame plaid is a bold street style choice. Depending on how you wear it, you might be referencing the London punk scene or fashionable Sloane Street. Mix and match your patterns with prints for a bit of fun, or make the jacket the statement of your wardrobe with a solid dress shirt and a tweed tie. London's calling, gentlemen.
