Wow! Hayley Atwell's Plunging Backless Gown For The Pride After-Party

Hatley Atwell was clocked leaving the opening night of The Pride at Trafalgar Studios last night looking super glam. The lady wore purple and the look was plunging (just the right amount of) AND backless.

Atwell plays part in Alexi Kaye Campbell's 2008 play which explores attitudes to homosexuality (pretty topical right now with THAT new Russian law) and after last night's performance joined cast members in holding mini banners banners that read: "To Russia With Love".

As far as after party ensembles go this was a sure thing - Atwell's purple dress with gold button detailing was teamed perfectly with nude patent heels, a silver clutch and bright pink nail polish.


Hayley was all smiles after curtain call; the press night performance was a total success which called for a whole lot of celebrating at The Royal Horseguards afterwards.

Here's a gallery of gorgeous pieces guaranteed to get Atwell's glam look...
