I’m not going to pretend that our great British high street will ever be the first port of call for high-tech, innovative fabrics - but if yesterday’s first showing of M&S’s summer collection was anything to judge by, remortgaging your house or even making that quick dash to Milan will not be necessary. Because, somewhere among the rails of coloured cashmere, endless shirting and mountains of six-pack G-strings, there’s a lot that you’re going to like about next season.

The sport-luxe references were present and correct: cream or white parkas with nifty bits of hardware and a crease-free finish gave a nod to Stella McCartney’s recent hit collections, from £39.50.

Seeking something a little more sophisticated? That’s where the neutrals, in seductive tones of faded plum, apricot or tea-rose on delicate chiffon blouses with jet-bead trims, were particularly welcome. Ditto the layered-cut aubergine and navy dress with its high-gloss finish, smart enough for a glamorous wedding and a snip at £89. The shoes and bags were increasingly on trend: cute patent flats in eye-popping shades of red, navy and a retro, rust tone (£29.50). And who can resist the Helmut Lang-esque elasticated sandals, a bargain at £45?

Kate Bostock, the creative guru responsible for M&S’s recent successful trajectory, said: “We’re pushing for more innovative fabrics, looking at different patents, metallics and synthetics, silks and even more leather. Now that there’s more confidence as a brand we can really push the boundaries. Better quality fabrics cost a little more but as long as the differences are discernible then customers are happy to pay.”

Indeed, the bags are guaranteed summer hits: flesh-coloured patent bucket shapes with contrast trim handles or an ombré shading technique not too dissimilar to the selection found at Marni and Prada. As for lingerie, the mix-and-match range at £8 for a bra and £2 for knickers seemed very good value. Even Autograph’s bewitching Forties-inspired underwear sets in cappuccino shades were reasonably priced, starting at £19 for a bra.

This strong offering comes on the back of a Christmas advertising campaign starring Antonio Banderas and the retailer’s established female cast in an affectionate homage to the film trailers of the Forties. The company is also in buoyant mood after a recent report of strong profits and a big move into international markets, completing its turnaround after the very public withdrawal from its international operations earlier this decade.

Yesterday it was announced that the British model Lily Cole will be the new face of M&S.
