oh and how's the weather in NYC during december? I'm going mid december, a few days before xmas. I live in the midwest and it's already snowing here. Is the weather better in the east coast or worse?
and also, where can you get good fitting I love NYC shirts? haha silly i know but I have a few ones from friends who have gone to NYC before but they're always so big. thanks
East coast weather is totally unpredictable that time of year. Sometimes it's below freezing, sometimes it's warm enough that you don't need a coat. Check weather.com before you leave and make sure to bring layers! It will probably be in 40's, but there's no telling...
You can find I

NY shirts and other souvenirs on the street.
As for sights, you HAVE to go to Rockefeller Center and see the tree! You can ice skate there, too. The atmosphere around Rockefeller Center at Xmas time is like magic IMO! The museums in NYC are spectacular, too. My favorites are the Metropolitan Museum of Art and the Museum of Natural History. Another fun thing to do is go to show tapings. David Letterman, Martha Stewart, Rachael Ray and others film their shows there & you can get tickets to be in the audience.
Have fun!!!
