This black embroidered shift dress from French Connection had long sleeves and a very modest neckline. The contrast in the embroidery colours against the black really gives this dress a sparkly but understated look. This dress retails at £200.
For something really glamourous, this 3/4 length dress silk from the See by Chloé collection needs no accessories. It's available in both black and blue and can be yours for the small sum of £318
