I'm going to prepare my bag for my USA holiday...but i don't know from where to start. I also need a Halloween costume, but i will arrive in Texas the morning of the 31st of october..someone has some ideas for me? I'm trying to imagine how it will be Halloween Party in USA...i'm very excited.....the only costume that i can bring with me it's a venetian mask with the mantel that i bought in Venice's shop which made masks for "Eyes Wide Shut" the movie....
I'm very very confused....i need some help PLEASEEEE!!!! It will be my first real Halloween!
I'd like also try to became a Tim Burton's character, but i think it will be very hard........ may i need to die before!
