Lily Allen Ends Her West End Run in an Ultra-Plunging Red Gown and Sparkling Diamonds

Following her final performance in "The Pillowman" on 3 Sept., Allen opted for old school Hollywood glamour. The star chose an ultra-plunging red silk Emilia Wickstead gown with Boucheron diamonds and matching red lipstick in a look that oozed fashion confidence. Long may her style reign continue . . .

On 1 Sept., Allen stepped out in an ice blue Giorgio Armani gown that dazzled on the London streets. The floaty dress included a layer of tulle covered in silver embellishments over a column of silk and could have been straight from the Disney film, "Frozen". She added statement earrings, a box bag, and icy makeup to complete the look.

For the last day of August, Allen wore a deep plunging Giambattista Valli dress covered in an oversized rose print. With a mini Self Portrait box bag, the voluminous gown made a serious style statement.

Nothing is as dramatic as a train on your dress, and Allen worked it as she left the theatre on 30 August. In an off-the-shoulder minidress by Vivienne Westwood with abstract floral print, the ensemble was given some added eccentricity via a long olive green train. Teamed with gold Christian Louboutin strappy sandals, Allen ensured all eyes were on her.

The cone-bra has been having a moment of late, with Rita Ora also rocking the look in the same dress earlier this year. On 29 August, Allen chose the white satin Richard Quinn dress that accentuated her chest with the 3D design. She added platform white heels to elongate the column cut of the gown and an Anya Hindmarch clutch bag with pearl embroidery.

Allen stood out among the crowds on 28 August in a bright yellow Giambattista Valli cutout dress. The flirty design included a ruffle down the front and at the bottom of the hem with cutout at the torso and chest.

On 25 August, Allen chose a voluminous Erdem gown. The orange hue was the perfect summer shade while the top half was overlayed with a white sheer corset bralet. With Christian Louboutin heels and Nada Ghazal statement earrings, she was dressed to impress.

A striking tiger print gown was the post-show look for 23 August. The GCDS design combined black and yellow for a statement look. The dress consisted of a low back with crossover straps to give it some added sex appeal.

Denim maxi skirts have been the piece of the season so of course Allen chose a Self Portrait design in a dark wash shade. Keeping to a colour scheme of white and navy on 22 August, she added a cropped boucle jacket with white collar and cuffs.

The 21 August was a Giorgio Armani kind of day. A black gown with sequin trimming was the chicest way we've seen to leave a theatre.

Allen opted for black and red on the evening of 18 August, stepping out from the stage door in a floor-length Clio Peppiatt gown with a cutout section at the side covered by star fish and seaweed embroidery. The asymmetric fitted dress was given some extra glamour with a pop of red lipstick and chic Jimmy Choo heels.

The ultimate summer look was the choice on 17 August as the actor wore a white lace co-ord from Self-Portrait. A perfect outfit for any brides-to-be heading on a hen do, Allen teamed it with simple white Christian Louboutin stilettos.

On 16 August, Allen wore an asymmetric black top from Magda Butrym with a rosette on the shoulder. Teamed with a pair of low-slung flared trousers and Messika jewellery, she looked chic in top-to-toe black.

Cutouts were the order of the day on 15 Aug. Allen wore a floor-length white knitted dress from Chloe with double cutouts on either side which could have walked straight out of Maya Jama's wardrobe. She paired it with statement earrings and a nude bag.

Allen opted for a matching jacket and skirt from Nafsika Skourti on 14 Aug. The black co-ord came complete with rows of semi-circle cutouts which she wore over a sheer top with strategically placed red flower embroidery. She added a red box bag to pull out the colour and finished the outfit with strappy Christian Louboutin sandals.

Allen made a statement on 11 Aug. with a floral hooded dress courtesy of Magda Butrym. The halterneck design came complete with a corsage at the neck. Allen highlighted the pink in the print with a neon fuchsia clutch bag and strappy heels.

On 10 Aug. Allen chose a pale lemon co-ord by Edeline Lee. The long-sleeved crop top perfectly highlighted her abs while the belted Fifties-style midi skirt was the perfect feminine accompaniment. Teamed with white court shoes and a whire box bag, she was the picture of spring.

Allen upped the ante with a risqué look on 8 Aug. Wearing a see-through open-weave Chloe dress over a crochet bralet and cycling shorts, her black thong was just about visible underneath the sheer layers. With platform black sandals and Shaun Leane jewellery, it was an outfit to turn heads.

Channelling the Barbiecore trend, Allen went super feminine in a Victoria Beckham satin midi dress on 7 Aug. The floaty fabric is oh-so-pretty while the fit cinches at the waist. Teamed with pale pink court shoes and bag, this was a look Margot Robbie would be proud of.

On 5 Aug., Allen sported a super chic bouclé cropped jacket and micro miniskirt from Self-Portrait. With sheer black tights and black court shoes, she looked every inch the fashion mogul.

Allen chose a plunging blazer dress on 4 Aug. by De La Vali. With cute bows at the bottom, she added platform black heels to complete the look.

Allen channelled the Y2K trend on 3 Aug. as she chose to go braless under a backless, semi-sheer, chainmail top. Teamed with baggy cargo pants and lilac peep-toe wedges, she gave a masterclass in retro dressing.

A micro Zimmermann minidress was the order of the day on 2 Aug. The super cute yellow floral minidress was teamed with clashing pink buckle mules for a summer look worth emulating.

Allen rocked a quirky black, collared crop top with high-waisted tailored trousers by Philosophy Di Lorenzo Serafini on 1 Aug. With her bob hair given a middle parting and kept sleek, the look was modern sophistication.

On 31 July, Allen chose a red strapless, crochet number by Magda Butrym. The open weave made for a slightly sheer effect, so she added high-waisted nude knickers underneath. Teamed with matching red Manolo Blahnik heels and jewellery by Messika, she looked super glam.

Proving the little black dress is a classic for a reason, Allen wore an off-the-shoulder dress by Vivienne Westwood on 25 July. Paired with a black choker with the iconic Westwood orb and matching bag, she finished the look with a red pop of lipstick.

Allen went suited and booted on 24 July in a checked two-piece by Alessandra Rich. The grey checked cropped blazer teamed with a midi skirt, and waist belt, was power dressing to the max. Statement earrings and pewter platform Jimmy Choo heels took the look from work to play.

Allen went bright and bold on 21 July in a Philosophy di Lorenzo Serafini strapless dress. The eye-catching hue was stunning, but it was the intricate scenery print that took this dress to a new level.

Allen jumped on the balletcore trend on 20 July wearing a pale pink look from top-to-toe. The Needle and Thread outfit comprised of a crystal-embellished cardigan with a ruffled maxi skirt.

On 18 July, Allen chose a pink diamonté bodysuit under sheer black trousers, but it was her frock coat that really stole the show. The Giorgio Armani design was straight from the Autumn/Winter catwalk and included a chic diamonté collar.

Adding some sparkle to the London streets, Allen championed independent label Nafsika Skourti for her look on 15 July. The silver sequin top of the dress moved into a voluminous black skirt with a contemporary cutout at the middle. Simply strappy heels were all that was needed to complete the look.

A super chic red hot look was the order of the day on 11 July. Keeping the dress in an off-the-shoulder style, the Philosophy di Lorenzo Serafini design was bold and beautiful. With flattering ruching and a full semi-sheer skirt, Allen added an embellished box bag for a look that was red carpet-worthy.

If there was ever an outfit to go straight on our summer list, it's this one. Allen chose a three-piece co-ord by Elie Saab as she left the Duke of York Theatre on 10 July. The white crochet bralet with matching high-waisted shorts and cute jacket would look just as cool in a beach club as they would for dinner plans.

Following a successful opening press night on 21 June, Allen wore a velvet Alessandra Rich gown. The ensemble was given a chic twist via sheer lace puff sleeves and panels down each side.
