Poppy Delevingne In The Perfect Day-To-Night Ensemble (PHOTO)

WHO: Model and socialite, Poppy Delevingne

WHAT: James Cook's fiancée attended a champagne reception celebrating the launch of the Thomas Sabo spring 2012 Jewellery Collection earlier this week. Her outfit is an ideal ensemble for transitioning from day to night. Poppy's simple jeans and grey tank would be great for a casual day at the beach (paired with sandals, of course). At night, a bright blazer, edgy boots and red lipstick make this look chic enough for a dinner on the town (or a champagne reception in this case). The fashionista's little black Chanel bag and long gold necklace added some personality, while her tousled locks made her stylish look appear totally effortless.

WHERE: Miss Delevingne was spotted in London on December 5th.
