Picking up her MBE from Prince Charles yesterday, Adele came in with glitzy guns blazing in a jewelled headband by Philip Treacy. Take a tip from the Most Excellent (of the British Empire) Adele, and let a single statement jewel do all the wowing. Actresses Jamie Chung and Lily Collins are single-statement jewel fans too. Jamie's giant sparkler of a necklace that she wore to a JC Penney event in New York and Lily's bling ear cuff worn at the Chanel Métiers d'Art show in Dallas have got 'copy this Christmas' written all over them. Simple but effective – we like.
