Unlike some more exotic places you might travel to, packing for London is a cinch. Since London is a huge metropolitan city, pretty much anything you forget to pack, you can buy in London. However, to save yourself a bit of money and grief, there are a few items you must bring with you.

Travel Adapter
Most people will bring a camera that needs to be charged, if not also an iPod, and other electronic devices. Bring a travel adapter that will fit into a British plug point and that also has a voltage selector so you don’t end up frying your electronic device.

Layers
Weather in London, even in the summer, can be very changeable. The day might seem sunny and warm when you first get dressed, only to have the weather change very quickly. Pack layers that you can add or remove easily so that you’re always prepared for London weather.

Good Walking Shoes.
You’ll probably find that you will do a lot more walking around London than back home. In London, most people either walk or take the buses or underground. Either way, you’ll find yourself on your feet a good deal of the time. In addition, the pavements in London can be uneven and a challenge to your feet if you’re not used to it, which is why comfortable shoes are a must.

Umbrella
Rain in London can come on in an instant. Even in the summer time, there’s still a good chance of getting rained on. Consider packing a small travel umbrella just in case. However, if you don’t have the room for an umbrella in your bag, don’t worry. You can pick up a cheap one at just about any London high street shop.

Evening Clothes
London is filled with pubs, clubs, theatres, restaurants and other night spots. Don’t forget to pack some appropriate evening clothes so you can enjoy all of London's nightlife.

Clothes for Wimbledon
Wimbledon how become more casual over the past few years, similar to the other Grand Slams. The key is to dress in layers. Having said that, the dress cose for the more exclusive areas such as the Debenture Seat Holders Lounge has remained the same.

Good Map of London
Tourist maps are notoriously vague and difficult to navigate with. Consider investing in a good map of London, such as a London A-Z.
