Want to upgrade your LBD? Take a tip from beauts French actress Léa Seydoux and team it with stand-out embellished heels for fierce night-time style. We're crushing on the Blue Is The Warmest Colour star's cobalt and gold peep-toes, but any colour works as long as it's eye-catching. Look out for lust-worthy details like an ankle strap, too. Add another colour pop with a vibrant statement lip, top off with an edgy topknot, et voilà. Chic-meets-cool evening look nailed.
