Margot Robbie drew widespread attention at a London film premiere this week when she arrived in a floor-length, sheer gown from Armani Privé’s SS25 couture collection that left little to the imagination.

The 35-year-old Australian actress wore a translucent, crystal- and sequin-adorned dress with an open back to the screening of A Big Bold Beautiful Journey on Thursday. The gown revealed a skimpy undergarment and exposed an ample amount of side and back skin; Robbie wore her hair up and accessorized with classic diamond earrings as she posed for photographers and smiled alongside co-star Colin Farrell. The appearance came after a recent break from public events while she gave birth to her son.

Reaction on social media was mixed. Some fans praised Robbie’s appearance and celebrated her return to the red carpet, calling her “breathtaking” and expressing support for her health and happiness after becoming a mother. Others criticized the revealing nature of the dress, saying it detracted from the garment’s detailing. On the r/popculture subreddit, commenters questioned the decision to wear such a transparent look, with one user writing, “I’m so tired of sheer dresses, it’s lazy shock design,” and another saying the exposed back took away from the gown’s craftsmanship.

Several users said the outfit seemed at odds with Robbie’s typically more conservative red-carpet choices, with some speculating about a change in styling. Others noted the practical discomfort of wearing such a dress; multiple commenters suggested she appeared uncomfortable while posing. A separate thread of commentary contrasted female red-carpet fashion with menswear, noting that male actors rarely wear comparably revealing outfits.

Photographs from the event show Robbie confidently posing for cameras, though the public response highlighted an ongoing conversation about transparency and provocation in couture. Journalists and fashion commentators have for years debated the place of sheer and skin-baring designs on red carpets, where designers and celebrities often balance craft, publicity and personal taste.

Robbie’s choice continues a broader trend of high-profile stars wearing sheer pieces by couture houses this season. Armani Privé’s SS25 offerings have appeared on several red carpets, drawing attention for their embellishment and construction as well as for how they are styled. Designers and stylists say the intent behind sheer fabrics can range from showcasing tailoring and embroidery to making a deliberate statement about body and glamour.

The London screening marked one of Robbie’s early public appearances since becoming a parent, and the publicity around her ensemble underscores how celebrity fashion moments can quickly become focal points for larger conversations about aesthetics and modesty. Organizers at the premiere did not immediately respond to requests for comment, and Robbie’s representatives did not provide a statement about the choice of dress or the social-media reaction.

As with many red-carpet looks, opinions split between admiration for the actress’s poise and concerns about the wardrobe’s level of exposure. The debate around Robbie’s Armani Privé gown reflects continuing tensions in celebrity fashion between artistic expression, public expectation and the scrutinizing lens of social media.
