Lili Reinhart arrived at the London premiere of The Love Hypothesis in a vintage Emanuel Ungaro gown so colourful and heavily embellished that one Reddit user joked it was 'giving lava lamp'. The actress wore the striking Spring/Summer 2001 design at BFI Southbank, turning a 25-year-old archival dress into one of the more eye-catching looks from her film promotional tour.
The look paired swirling shades of purple and blue with intricate embellishment, while the absence of a necklace allowed the dramatic neckline to stand out. With Giuseppe Zanotti shoes completing the outfit, Reinhart's styling gave the archival gown a fresh red carpet moment without drowning it in extra accessories.
Reinhart Brought Vintage Ungaro to London
Reinhart wore the vintage Emanuel Ungaro Spring/Summer 2001 ready-to-wear gown for The Love Hypothesis at BFI Southbank in London, where she appeared alongside co-star Tom Bateman. The look was styled by Ib Abdel Nasser, with Giuseppe Zanotti shoes providing a carefully matched finishing touch.
The gown comes from Ungaro's early-2000s fashion era, when bold colours and elaborate details could make a statement on the red carpet. Rather than choosing a predictable modern dress, Reinhart's team reached back to an archival collection and allowed its unusual palette to become the main attraction.
The Colours Prompts the Lava Lamp Joke
The combination of purple, blue and bright embellishment prompted playful reactions from some users discussing the look online. One Reddit commenter wrote that the colours were 'giving lava lamp', turning an unusual fashion description into a memorable reaction to the outfit.

That comparison was clearly a playful opinion rather than a literal description of the gown, but it captures the look's psychedelic quality. The bold colours appear almost to shift across the dress, giving the otherwise elegant silhouette an unexpectedly energetic visual effect.
The Gown Is Covered in Tiny Details
The column-style dress is far from a simple block of colour, with beading and fringe adding texture across the design. Another Reddit commenter praised the colours, beading, matching kitten heels and fit, while giving the overall look a 10 out of 10.
The neckline also became part of the appeal because Reinhart did not add a necklace. Several commenters specifically liked the bare neck, suggesting that the gown already had enough patterns and embellishment to make additional jewellery unnecessary.
The Matching Shoes Keep It Together
The Giuseppe Zanotti shoes were not simply an afterthought, with their colour helping connect the footwear to the gown. Some Reddit commenters noticed the match, with one highlighting how well the shoes picked up the green tone in the dress.
That small styling choice helps explain why the maximalist gown does not feel completely chaotic. With the dress already carrying so much visual information, the matching footwear reinforces the palette without introducing another competing colour.
The Look Still Feels Very Early 2000s
The gown dates back to Ungaro's Spring/Summer 2001 ready-to-wear collection, placing it firmly within the early-2000s fashion era. Some commenters also viewed Reinhart's recent promotional wardrobe as a fresh take on the period without making the clothes feel like an ironic costume.
Another commenter described the outfit as giving 'science in a cool aesthetic way', an amusing observation given that The Love Hypothesis centres on a scientist. The remark is a fan interpretation rather than an established design detail, but it adds another layer to a look already packed with colour and personality.
Ungaro's Theatrical Past Lives On
The Spring/Summer 2001 collection gives Reinhart's dress a striking fashion history, reflecting the kind of extravagant colour and fantasy associated with Ungaro's work during the period. Bringing one of those archival designs into a modern film premiere also highlights how dramatically older fashion can be reinterpreted through contemporary styling.
More than two decades later, Reinhart has given the design a completely different setting at a London film premiere. And while one Reddit user may see a lava lamp, the appearance shows how archival fashion can still feel surprisingly fresh when the colour, styling and attitude come together.
