Turns out there was a bug in the pattern I didn't find out till later. I made the sleeves and dress longer, because according to their sizing I'm 38(!) but that's because I have no chest and no hips. I think all up it took me ~16 hours but it was quite the learning experience. I now understand what those pattern books are talking about (there's 7 segments going around the body, doing shaping I don't actually need).
The fabric was my choice, why go for a solid colour when you can have a pattern

For my next project it's either going to be some kind of wrap skirt or some kind of swimwear. The RipSkirt mentioned elsewhere looks attractive, but for the price + shipping and handling to here I can buy very many square metres of material and it doesn't look too complicated.
But lo, according to their site they start distributing in Europe in the spring, yay!
