What to bring for my trip to London over New Years?

I spent the summer in Europe, and I spent A LOT of weekends in London. I would recommend that you bring skinny jeans if you have them, as a lot of girls wear them over there. It isn't super cold, but it does rain frequently. If you waterproof your UGGs, you could possible take them. I actually bought some great wellies (rain boots) while I was over there, and if you got some boot liners, they would be great to take if you have some(but hard to pack, you'd have to actually wear them). Layers will be a good bet, so if you want to layer sweaters over tees, and then toss a warm, waterproof jacket on over that, you'd stay warm and dry. Right now, it's about 45 degrees in the day, but it'll probably be a bit colder over the new year. Also, pickpockets are only bad in touristy areas, so you should be safe with a good bag that zips up. No open totes! I took a backpack with me on a few trips, and I just used a little travel lock to secure the zippers. Bring a money belt if you're really worried. Most important, have fun! London is a great city, and there's so much to see and do!
