Winter jacket for visiting to Paris from November 20 to November 26?

I'm a layers person, always. Packable layers (puffer jacket and waterproof rain jacket). But if my whole trip was a week in Paris in November, I might choose something more geared toward the cold and maybe a little more stylish like a wool coat. I'm normally anti-umbrella, but in this scenario, I can see one being useful for the "chance of rain."

That's a high in the 40s in Paris tomorrow and the next few days. I just finished watching the weather report here in France five minutes ago, and the next few days will be in the 30s in morning and 45 in the afternoon. And rainy.
You will need the waterproofing, something to cut the wind, but also layers that can be opened or removed. And don't forget very important gloves, hat, and neck scarf.

I was in Paris a few days ago and wore my wool mid-length coat with a scarf. I did take an umbrella but, honestly, it was too crowded and a bit too windy for it to be useful. I also dressed in layers as some of the venues are warmer than others. I did get caught in one downpour but was quickly able to hop under some covering and did not feel I needed something waterproof. Enjoy your trip!

It depends a lot on you. Do you tend to be cold? If so, then yes maybe a heavier wool coat. I find the problem with heavy wool coats is that, when you go indoors, such a shop, it's too hot. Plus, when they get wet, they're even heavier and, of course, not waterproof.

That's when layers might better. I tend to be warm, so an unlined or boiled wool coat suits me better. They're lighter and, with a sweater underneath, I'm fine. Plus boiled wool sheds water because it's knit so tightly. YMMV

Layers are a must. It gets ungodly hot in the buildings with the French heating systems. They complain about extreme temperature changes when going into the air conditioning, but not for heating - strangely enough. Something about their livers...

Something about their livers... LOL, LOL, LOL

Anyone in a relationship with a French person and who has French in-laws has heard about the liver.

Don't worry Alexander, a shot of something will take care of it. A restaurant chef set a bottle of Fernet-Branca on the table for my 18-year old to drink for a cure at Christmas lunch when his little liver had been allergic to some scallops Christmas Eve.

Thank you for all of your replies. Looking forward to our trip.
