Proper, proper 
at your sweater collection here, too.
Thanks, AuldA, I'm sure I'll chance upon a Monoprix and have a look. The weather promises to be colder and colder, possible wet snow at the end of the week. So definitely lots of layers, I'm shite with them though as they're really uncomfortable when cycling (you basically end up overheating with thermals IME) so I only ever bother with them below freezing or if I'm in Scandinavia. Temperatures aren't that different to here though, and Paris isn't near any coastline so I doubt it's going to feel colder.
Sock, interestingly enough like Inis Meain, Le Tricoteur is really popular in Japan too.
I do sometimes wonder if people still actively buy white underwear. I've always had the option of nude (which I think is a more 'recent' staple colour) so have never seen the point of white, as it generally is visible underneath white regardless. Don't really like it as a colour on my body much either but I guess the opposite would be true for others. It just feels very bridal to me.
I think what's good about understanding your own body shape is that you stop looking at a model and seeing all the things you 'lack' when you may very well have the same shape but height and weight differences make that more difficult to see. The opposite is true too. If a model has very wide shoulders and you don't, depending on whether that fits her ok-ish or fantastic helps sort out what it will do for you.
I find the whole trend of exercising/weight training to get a specific body type really disconcerting, quirky. We can't retro-engineer ourselves into something we're genetically not, plenty cashing in on selling this dream regardless, unfortunately.
Proportionally and shape wise swimsuits are quite a complicated subject to tackle (from an aesthetic POV) as you pretty much have to reverse your thinking, as you're basically uncovering rather than predominantly covering. Think Justine did an interesting video on it but I thought some of the suggestions for body types weren't the best.
Elle, well if we are discussing more conservative office wear, can I just mention Christine Lagarde. Who I always feel really bad for discussing in terms of only style or fashion as it's probably the least impressive thing about her.
The woman beside her, Rachida Dati, was also interesting style-wise during the Sarkozy presidency when she was Minister of Justice. She was also pregnant at the time, although she insisted on wearing her toweringly high heels throughout so not sure how helpful that is as inspiration. She definitely has a harder edge around her (the leather blazer looks great against the bump IMO), where Lagarde can be a bit softer (except the signature hair) but has a lot of fun with flowier (but still structural) fabrics, scarves, and shoes.
I think it is difficult though as a lot of style images we have available to us are the bloggers (who rarely specialise in it and when they do often feel a bit DoC) and the Royals who are always a touch more dressed to occasion than business (although our Queen Maxima did use to work in finance and that will occasionally peek through). You have the odd silicon valley CEO/CFO or whatever but they're usually a bit dull. Ditto for politicians. Obviously, the style/fashion tastes of these women aren't of chief interest but the fact that women are so underrepresented in high ranking positions explain the scarcity of those images as well.
The Chloe blazer is working well for you though, isn't it? I think a work wardrobe is more challenging as you do have to take your environment into it far more than elsewhere. They don't call it power dressing for nothing, there needs to be space in the room to allow for it and you have to be comfortable taking that space.
I did see a Dries blazer online the other day that I thought would be great for you, but you did mention having shopped enough, so have kept shtum. Was also a size 36, not sure whether that's your size or not, but will look it up again if you like?
