Silk dresses aren't the most practical of investments. The moment you sit down they start to crease around the stomach and waist so it may not be worth spending much on a silk garment. That said, it's a notoriously difficult fabric to sew, so you really have to watch the quality of the finish. Weighing those two options up, you might decide you want to splash out, in which case See by Chloe's black silk dress is a beautiful shape and cut for £260. If you'd rather go cheap, River Island have a very similar style in a more eyecatching colour for only £30. Wrap the ties all the way around so that they tie at the front, and you'll have an almost idential style for a fraction of the price.
