Is it just us or does it feel like we haven't seen Sienna Miller in an age? Well, what better way to make a comeback than in an oh-so stylish Topshop (score!) LBD at Vanity Fair's Tribeca Film Festival party in New York...
The actress was looking more than amazing in a floral-detail black minidress teamed with enviable satin pumps made good with ma-hussive gemstones.
Accessorising her outfit with a cute colour block cross-body bag and opting to go almost jewellery free the star was fresh and fancy free.
The 31-year-old also went au naturale with her beauty look. Sienna was glowing with next-to-no slap on her gorgeous face. When you've got such a great base to work with a lick of pink lippy and mascara is all you need, agreed?
