You can add a delicate belt, maybe made of metal or fine faux leather to add some detailing to the dress. This will also help to bring a slight amount of flair to it and make the silhouette more flowy. Pair it with mid high heels or you could even wear block heels or wedges with it. You could also carry a nice statement clutch with it as an accessory for a night out on town.
For your makeup, you could use a bright pink lip colour and use brown eyeshadow for a smoky eye effect. Jewellery can be kept simple and classic. Since the dress has a sheen to it, you could stick to any white metal jewellery. Delicate silver or platinum jewellery with precious or semi-precious pearls or crystals would jazz it up just the right amount!
