Don't worry!!! I travel all over the world (Japan, UK, US, ect) constantly. I travel well dressed with all LV, never had a problem, They are a little more concerned with terrorism these days, the only way you would get pulled for a bag, is if you had a suitcase full or a suitcase full of fakes. As long as your bag doesn't have any exotic skin on it, like lizard and such, you won't need papers. Dress up and have fun!
