Is this enough for Paris/italy?

I’m going for a week, leaving tomorrow. It’s my first time leaving the country and I’m so nervous. I packed pretty light. 5 long sleeve shirts, 3 tanks, 3 cardigans, 1 jeans, 1 leggings, 1 sweatpants, 3 jackets, 4 dresses, 3 skirts, sneakers and fancy shoes. all of this fits in a tiny carry in bag and weighs only 15 lbs. im nervous im not packing enough stuff. im so scared i forgot something and im gonna look weird and not fashionable.
