What to wear in Paris? In one word - BLACK. Perferably a shortie quilted BLACK jacket. Wear a shortie quilted black jacket whilst riding a Velib and you're set.
Here's Susan Hochbaum of Pastry Paris fame blending in nicely...
You could get away with pushing a black pousette with a smidge of pumpkin in it...
Black lace anything is 'in' right now, under or over...
Black ballerinas? Save them for summer.
It's boots, boots and more boots.
A small white dog is fine as an accessory...
At any time in Paris.
If you insist dressing like a Parisien by all means get a giantplans/maps of Paris (Thank you Grace!). People, Parisiens included, will be asking you directions. You better be prepared.
