Take for example this dress. I think you can rarely go wrong with a silk dress, especially when it's seriously reduced and the new season is all about prints.
I paired it with a fake fur collar as it's exactly the same colour as one of the flowers on the print and I thought it brings it out nicely. No jewellery needed.
