Well, I've made the mistake of looking at the very gorgeous Brora, Paisley stoles, they do look great with tweed! My jacket (above) is one I wear most years, it's at least 13yrs old, but not proper tweed, in that it's 40% wool and 60% acrylic/polyester, I think. Also, unlined, so not very warm. Which I think comes back to bo's point about fit and traditional, heavy tweed, when I was looking for a tweed jacket at the time, I was prepared to splash out on a more expensive one, but they all looked very frumpy and not very tailored,so I ended up with a "fashion" one, even so till it's lasted well. Anyway, I ended up wearing it yesterday with a small, grey, paisley scarf, pale denim flares and pale grey trainers, trying to dress down the formal tweed and lighten it up as it's still summer-ish.
To answer about curls, both pregnancies were girls, so no difference there, I just think my hair is very susceptible to hormones. I'm not sure about the porosity test, my hair definitely floated (though, maybe I should try again when it's freshly washed, no product) which is supposed to mean low porosity, but it fizzes like mad in humidity and soaks up oil like no one's business, which surely means it's porous

Love the cape, Gah and all the other pics. Elle you always look very chic. I agree with flo this thread discusses some very lovely, interesting clothes and how they work on our bodies.
