Oh wow, this sounds like a great trip and (as a French lady), I hope you'll enjoy France!
With regards to the outfits in the photos, I second pirouette : not all women you'll see in France will be dressed like that. However, I'm pretty confidend that some of them will be.
To me, not all outfits appear to cater to the same context / places though (but that's just a personal feeling) :
- #1-3-5-6 and 8 absolutely look like what many women do wear in my area (the rather chic countryside a few dozen kilometers away from Paris) to go to the restaurant, or even simply for a downtown trip. #1 is essentially my MIL's summer uniform in Fontainebleau : flowy midi skirts, espadrille wedges, interesting tops.
- #2 is more boho to my eye and I would associate it with Southern France. By the way, you should see this beautiful golden ochre colour a lot in Provence, especially on traditional fabrics.
- #4 looks trendier and more "new money" to me, and I would associate it with a more glamour setting. But perhaps that's because I was raised to keep jewelry understated.
- #7 and #9 scream "Parisian" fashionista to me - fashionable and original. I have not really seen people dressed like that around here.
