Demi Sims was clearly in a nostalgic mood on Monday night, as she posted a series of throwback snaps, including one of her as a 16 year old at prom. The 25 year old The Only Way is Essex star took to her Instagram stories to post a prom photo of her posing with her brother, Charlie, who also appeared on TOWIE. The then-youngster wore a slinky white halter-neck sequinned dress with towering platform heels and she beamed as she wrapped an arm around her big brother.
