Lily Allen wears receipt dress with David Harbour diss track lyrics on ‘West End Girl’ tour

Lily Allen’s latest revenge dress comes with a paper trail.

The singer, 40, kicked off her “West End Girl” tour at Glasgow Royal Concert Hall on Monday, performing her David Harbour breakup album in a series of costumes that hit just as hard as the lyrics.

During “4Chan Stan,” Allen wrapped herself in a long swath of fabric printed with handwritten lyrics and receipts from tequila bars and Bergdorf Goodman — the latter a direct nod to the track, in which she discovers her husband bought another woman a pricey handbag at the luxury department store.

Allen wore the damning “dress” over the custom Self-Portrait ruffled sheer lace bodysuit, burgundy patent hot pants, Agent Provocateur bra, Calzedonia fishnet tights and Christian Louboutin pumps she’d debuted during the previous numbers.

The show’s looks were styled by Mel Ottenberg, the Interview magazine editor-in-chief, who said on Instagram that Allen “got me out of tour styling retirement 20 years after I first styled her.” Makeup artist Aimée Twist and hairstylist Ross Kwan rounded out the glam team, with Kwan sculpting Allen’s hair into a bouffant with bangs for the show.

She performed all 14 tracks from the album — widely understood to chronicle the breakdown of her marriage to the “Stranger Things” actor, 50 — cycling through six looks over the 45-minute set, each tailored to a different chapter of the record’s narrative.

For “Madeline” — the track about the mystery woman she discovered in her husband’s text messages — Allen performed in a sheer Valentino negligee paired with Araks bra and underwear and marabou-trimmed Manito silk robe on a pink-lit stage.

She emerged in a pink tweed Valentino skirt suit with an oversized black bow at the top of the set and changed into a black leather bullet-bra bustier dress by 16Arlington — whose runway show Allen walked in November — for “Beg For Me.”

During “Pussy Palace,” Allen sang from a bed onstage, a Duane Reade bag beside her — mirroring the track’s lyrics about discovering a shoebox full of love letters from other women.

The pop star previously performed two tracks from the album on “Saturday Night Live” in December and dressed as the children’s book character Madeline for Halloween — a pointed wink at the album’s “other woman.”

Allen has since moved on with Jonah Freud, a 28-year-old London-based writer and artist and the great-great-grandson of Sigmund Freud, whom she confirmed as her boyfriend in a recent Grazia UK interview.

The tour continues across the UK through March before heading to North America in April.
