That's lovely, TheJumped, thank you. It's my aim for the blog (and, soon, the rest of the website) to be useful.
I would return something, too, if it didn't wash properly. £35 cost per wear is pretty high, otherwise. On the other hand, I wore a Banana Republic viscose crepe blouse yesterday. It does crease, but not badly (although wouldn't buy it again) and washes well. It is fairly thick, but I do wonder if it will just wear away to a thin rag over time. It feels fine on, though, so no problems re wearability (unlike poly).
I was thing that, ideally, manufacturers would do better composite fabrics. So, silk w some cotton and a little poly, for instance, so that it's slinky but durable?
