The American actress was brave enough to leave part of her bare bottom on show in the floor length coral dress, that boasted cut out leaf detail.
The gown had cut out panels around her waist, bust, bottom and back area and the sleeves displayed the pattern too.
No underwear necessary: Margo Stilley wore a coral dress with a revealing cut out leaf detail, that left a lot of her skin on show, on Thursday night.
Margo wore the eye-catching ensemble to attend Gabrielle's Angels Foundation UK Gala in London.
The event was held at Battersea Power Station and Margo joined the likes of Noomi Rapace, Tom Hardy and Sarah Ferguson.
