Lily Allen Wore 16Arlington To The Royal Academy Summer Exhibition Preview Party

Lily Allen attended the Royal Academy Summer Exhibition preview party held at Burlington House in London on Wednesday.

The singer wore a custom 16Arlington look inspired by the brand’s Spring 2026 collection.

From the lingerie-inspired slip silhouette to the feather embellishment sweeping across one shoulder and trailing behind her, it carries all the signatures that have made the label such a favourite among women who want something glamorous with a mischievous edge.

I much prefer the longer proportions of Lily’s gown, I’m also relieved they left off the feather-trimmed hemline from the original design. Between the shoulder embellishment and the feather train, there was already plenty happening. Adding feathers at the hem might have tipped the look into overload.

More importantly, this feels completely in tune with Lily’s personal style. There has always been a playful sensuality to the way she dresses, and this look taps into that.

For me, this is one of those celebrity-designer pairings that simply makes sense. The dress feels unmistakably 16Arlington, but it also feels unmistakably Lily Allen.
