There's an amazing Peter Lang piece that would look great. It's got huge black stones around the neckline and a ribbon to tie at the back - will be on the site to buy soon! I'd love to see black accessorised with this. I also think the big cream bangles they've got with it are pretty amazing, it keeps the whole thing fresh. Pearls would also do the trick - earrings and a bracelet. The key is to try and keep it modern. A simple clutch, a simple strappy shoe - nothing fussy 'cause the dress has a lot going on. I wouldn't do a covered nude shoe like in the picture though, I'd do something with just one strap across the toes and an ankle strap - or something as bare as that.
