Ahem, I'm also a Pilates fan I'll have you know - I even hopped on the train to be an instructor which now has me panicking because I realise how little I know haha. My current obsession in training and instructing - keep the chest open! My current and recurrent challenge - feeling secure in finding my neutral pelvis. For some reason this is really hard for me.
I think the magic circle is too big for a lot of people "at first" (which can be for a long time). Try a soft inflatable ball which is more flexible and easier to press together. We have a new AMAZING instructor where I train and instruct who had a small and helpful tip: heels together, toes apart, but your ankle bones are attracted to one another like magnets. That's the squeeze. Then your entire inner leg connects and you find your backside and your back. The magic circle I find can keep the legs too far apart which makes it more difficult to find the squeeze, easier with a smaller ball or even a rolled-up towel! My opinion is that props should not be introduced too soon actually haha.
But yes, a good instructor makes A WORLD of difference! Excuse the digression. Perhaps a separate thread somewhere is needed. 
Breasts: even if big ones have a moment, they are never ever considered chic are they, not in the French sense. Women have been made to feel bad over big breasts for forever. Source: all the vintage sewing and fashion blogs I used to read ... (Love the white jumper tho!) So in that sense too I can side with all my sisters who try to make big breasts chicer ...
The frambooze dress looks great in person, I must go in and see if it's arrived here. Did you snap a sneaky pic of her? :) Speaking of magic shorts - after putting an extra elastic band in my Arket trousers I think my Thing is going to be inserting hidden elastic into trouser waistbands, from hip to hip. Found tutorials online, so obvious really. I like the earrings, will go in and have a peek actually.
The Vagabond sneakers are nice but all the youngsters wear them here so I'd feel like a sham, but they're def Cool Approved, my shoe-savvy daughter would approve.
ethical clothing: Reduce, reuse, recycle, I suppose. My knowledge of quality comes in part from my mother, who did recognize it but wasn't interested in clothes or fashion at all. I've also worked at a dry-cleaner and picked up a lot there. Working there really brought home that expensive is not the same as quality. And quality is very hard to find these days. So I find myself in a conundrum - I'm not willing to pay through the nose for stuff I see isn't that great yet I can't find quality I want to buy. I'm left with very ordinary high street options but I try to shop second hand and take care of my clothes.
Lost track now, will just post!
