Clothes for Paris

Way back in my twenties, when I lived in France, I stopped wearing dresses to Paris because I found I got hassled by creepy guys, even if the dress was really modest.

I am excited to be going on a trip to Paris next week, but wondering if I dare wear a dress as I'll be travelling alone. Are there any fewer creeps in Paris than back then? Will being in my 30s take me off the creep radar?
