I've bought this dress from Cos www.cosstores.com/en_gbp/women/dresses/product.folded-collar-draped-dress-charcoal.0586125011.html - and want to dress it up a bit. I can't work out whether something like a choker worn next to my throat or something big and bold to be worn outside the folded collar would look better. Or neither, and I should concentrate on handbag and shoes... Any advice gratefully received!
