Marks and Spencer has us well and truly in the holiday spirit with its new M&S Food advert. Starring Dawn French, the advert highlights the selection of festive food on offer at the retailer for Christmas – but it’s the comedian’s outfit fashion fans have been eyeing up.

In the first of a six-part ad series, an exhausted French woman finds herself already hum-bugging over festivities until her fairy friend steps in to help transform her home and outfit into something more party-appropriate. In the blink of an eye, the 67-year-old goes from wearing a pair of checked pyjamas to a glitzy dress fit for a Christmas party.

Commenting on the advert on Instagram, fans have swooned over her glam look, commenting: “Can we get a link for the dress she is wearing, please?” and “Are Dawn’s dress and sparkly earrings available?” The good news is, you can indeed pick up Dawn’s festive frock, and for under £50, in fact. The Textured V-Neck Midi Relaxed Dress comes in at £45, and is said to ‘channel effortless glamour’.

The black midi dress is made from a shimmering textured fabric, making it really understated but elegant. Featuring a flattering V-neck and an effortlessly chic tiered skirt, it comes complete with voluminous sleeves for a touch of current trend appeal, reports the Mirror.

The piece is fully lined too, ensuring ultimate comfort and making it a superb choice for any fashion fan. Available from size 8 to 20 (sizes 22 and 24 are sold out), savvy shoppers need to act fast, as the sizes are flying off the shelves.

While it hasn’t amassed many reviews yet, one candid customer shared their thoughts: “Sadly this dress did nothing for me so returned. It was a little short in length, the fit was OK, the style appealed, but just did not suit me.”

Alternatively, River Island’s Black Velvet Drape Midi Dress or perhaps Next’s Black Sequin Maxi Skirt (£60) could steal the show. But for those wanting to channel Dawn French’s festive glam, grab her inspired outfit for £45.

Plus, with any purchase over £35, the beauty advent calendar – crammed with goodies worth over £300 – can be yours for just £50. What’s not to love?

The beauty advent calendar includes 25 products, with six full-sized items to indulge in as you count down to Christmas. Inside, shoppers will find a mix of well-known and emerging brands, including Clinique, Benefit, REN, Prai, and more.
