What colour should I paint my nails when wearing a nude dress and gold sandals?

My sixth form prom is taking place at a wine bar so it's not going to be particularly classy but I still want to look nice, I'm going to be wearing this dress: http://www.janenorman.co.uk/fcp/product/buy-fashion-look-fabulous//folded-bust-detail-dress/9284 and these sandals: http://www.bhs.co.uk/mall/productpage.cfm/bhsstore/282255/220607 but I have no idea what to do about nails. I have pale skin and blonde hair and I'm going to be going for brown eye shadow and natural lip gloss but am not really into gold or brown nail varnish - I was thinking maybe something along the lines of a soft pink-grey? Please help me with some ideas!
