oooh - lovely -is it chocolate brown ? perhaps something round your neck or maybe a glittery scarf thing (long - to wind round neck,or drape over shoulders). I don't like too many jewels at once ! Hope you're feeling better after the other day's trauma by the way.
How about some metallic bronze/pewter/silver sandals/mules/peeptoes, they had lots of choice at reasonable prices in Dolcis a couple of weeks ago. And cheap as chips but good for a one-off at New Look too. I recently bought some high metallic gold peeptoes to go with a similar dress, thinking I wouldn't wear them again, but I've decided I love to wear them with jeans and a plain top for pub nights etc.
yes NICE! also, and I know other mumsnetters wouldn't approve, but New Look actually do some good shoes - cheap as chips and ok if you're not going to wear them often - I bought some great sparkly silver shoes from there recently like the next ones in the pic
Forgot to say - a wrap would look lovely with that dress. Julien Macdonald does some nice ones for Debenahms - about £18 but if you're lucky you can find them for as little as £6 if the sale is still on. I was really pleased with mine, cream with burnished gold embroidery.
