Putting on a leggy display in a sheer flower-encrusted gown, the ethereal piece featured a slit slashed high on the thigh.
Cinched in at the waist with a wide leather belt, she added a Gothic edge in black platform shoes and a racy PVC mac.
With her brunette shoulder-length hair in tousled waves and wearing a touch of blusher, the actress put on a glamorous appearance.

Lily has been open about her battles with anorexia and bulimia and has penned a memoir at the tender age of 27.
And last week Lily revealed that she can count former Michelle Obama as one of her many fans.
The actress delightedly told her Instagram followers the former First Lady had penned her an 'epic' letter of encouragement.
Lily sent a copy of her memoir Unfiltered to Michelle, who wrote back to tell Lily she looked forward to sharing the book with her daughters Malia, 18, and Sasha, 15.
Telling fans about Michelle's letter in an Instagram video and the Rules Don't Apply, she could barely contain her delight.
In the clip, she read out Michelle's letter without telling her fans who the letter was from and when the big reveal came, Lily could not help a grin from spreading across her face.
Michelle wrote to Lily to thank her for sending the book and it seems that she did indeed read it.
'I am writing to thank you for the copy of your new book,' the former First Lady began. 'The gift was such a nice gesture and I look forward to sharing it with my daughters.
Passion for books: Michelle spent her tenure as First Lady promoting the need for all girls to have access to education so it is no surprise that she took an interest in Lily's book
'The outpouring of support I have received from women across the country continues to amaze me and I am filled with a great sense of hope for our shared future,' Michelle continued.
'I heard this quote recently and it reminded me of your book so I wanted to share it with you.
'"Here's to strong women, may we know them, may we be them, may we raise them."'
Michelle ended the elegantly written note by thanking Lily for sending her the book.
'Again thank you for your kindness Lily. I wish you all the best.'
Delight: The actress couldn't wait to share the news of her very important fan with her Instagram followers
Lily was astonished that her role model had written to her and quickly took a picture of the letter which she shared with her 6.5 million Instagram followers.
She captioned the image: 'Thank you from the bottom of my heart Michelle Obama for your encouragement and support. You have no idea how much this means to me.'
One thing that particularly delighted Lily was that Michelle's letter was posted with a Wonder Woman stamp.
She added: 'And that Wonder Woman stamp is everything. You truly are such an incredible inspiration. I'll definitely be framing these! #Unfiltered...' (sic)
The star added in a separate post that receiving the letter was the 'best way to start off my week'.
Incredible! Lily refused to tell fans who had written the letter as she read it out and when she revealed that it was in fact from Michelle Obama, she beamed in disbelief

She wrote: 'I can't believe this letter I received from someone I deeply respect and admire. It's absolutely epic. I'm in complete shock but just had to share!'
The star's latest film To The Bone, which sees her plays an anorexia patient, has seen her drawing on her own experiences after suffering from a secret eating disorder when she was a teenager.
Lily published her memoir, Unfiltered: No shame, no regrets, just me on March 7 which made a series of revelations about her life.

The actress made public a letter to her father - British musician Phil Collins, 66 - whom she said she forgave for being absent from her life as a child.
'I forgive you for not always being there when I needed and for not being the dad I expected,' she wrote in the book.
'I forgive the mistakes you made. And although it may seem like it's too late, it's not. There's still so much time to move forward.'
She told People: 'It’s definitely like having my diary published.'
