Olivia Wilde showcased her sleek style at the Fashion Trust US Awards in Los Angeles on Tuesday.
The House star, 39, looked confident in a high-necked, conservative black dress with a floaty bottom and chic bell sleeves.
The actress, who recently shared sizzling bikini snaps on her Instagram profile, added height to the look with a pair of extra high black platform boots.
Wilde wore her brunette tresses in a stylish updo, with a few strands framing her face in front.
Earlier in the day, the mother-of-two jokingly joked about the “Tramp Stamp” dragon tattoo on her butt in a cheeky post celebrating her birthday, which took place just over a week ago.

The entertainer – born Olivia Jane Cockburn – wore striking makeup, with black eyeliner drawing attention to her magnetic blue eyes.
Fashion Trust US is a non-profit organization dedicated to “discovering, funding and nurturing young design talent with the goal of helping them grow their label into a thriving global brand.”
Launched back in January, it encourages aspiring designers to apply to win “financial grants and mentorship in budget, strategy, digital, merchandising and general business support.”
Other stars of the event included Kate Beckinsale, Heidi Klum and Alessandra Ambrosio.
Olivia, who split from singer Harry Styles in November, took to Instagram on Tuesday to showcase a tattoo of a dragon on her butt, which she got when she was 13, ahead of attending the event.
She wrote: “39 and feeling fine. Thank you for the birthday love. I milked it way too long and it was great. To what’s next. Probably not another tramp, but who knows. #shameless #howdaresshe #thehorror.’
The snap next saw her posing from the back in a white thong bikini alongside a friend in a swimsuit.
She previously spoke about the ink while appearing on The Craig Ferguson Show. “I have a tattoo of a dragon that I got when I was 13,” she told the host.

“Who would tattoo a 13-year-old girl?” Ferguson asked her at the time.
“You have too much money, they’re going to tattoo a cat,” she replied, joking that while it “had a lot of meaning then,” she now found it “abominable.”
‘Where is it?’ he asked.
“It’s on my lower, lower, lower back,” she replied, adding, “It’s not a tramp stamp.” However, the host chimed in, “Yeah, it is!”
She also recently shared a series of stunning bike snaps and appeared to be having a blast on a sun-soaked getaway with friend Molly Howard over the weekend.
It comes amid reports that she is in “constant communication” with ex Jason Sudeikis, with whom she shares daughter Daisy, six, and son Otis, eight.
A source close to the former couple, who are both “very single,” insisted the couple “has no more drama.”
The two sparked speculation that they were on their way to a reunion in January when they were spotted being very touchy about one another in Los Angeles. However, the source noted that they are not currently in a romantic relationship, instead focusing on ‘friendship.’
