What I have bought.

I realised that I didn't care so much about the 'not black' part of the dress requirements, so ordered a black with pink spots swing dress, a black shirt dress, a blue dress with spaceships and a black wiggle dress because although it ticked even fewer buttons, it's cute and it's £9 and it still covers collarbone-elbows&knees, which is the main thing I was lacking.

And hopefully I won't need to do any shopping for a couple of years, and I also hope I haven't bored you too much.
