I am going to Paris in April of next year. What should I bring in my suitcase?

I am asking more about clothes but, if you have any advice about others it is welcomed. In the States, I consider myself stylish, others say the same. I have a kind of random style, little boho, little retro, little feminine, little artistic. So, in Paris I want to be on the stylish side. I don't want to look like a tourists. I want to look like the chic traveller!! THANK YOU!
