MY invitation to this year’s Met Gala must have got lost in the post, which is just as well, since I’m exhausted just looking at the eye-wateringly bonkers outfits on display at fashion’s biggest night.

Kim Kardashian rocked up in a Balenciaga “faceless custom ensemble” - a bodysuit with matching black mask covering her face, and a floor-length ponytail. Rapper Lil Nas X arrived in a huge gold cape, with Versace armour beneath, and Kendall Jenner wore a crystal embellished “Naked Audrey Hepburn dress” which was more ‘naked’ than ‘Audrey’ - ‘YOU too can look like Kendall (in trusty shapewear’), declared a press release, rather optimistically, in my inbox - while Rihanna was draped in a black over-sized coat dress and her boyfriend Asap Rocky was wrapped in a multi-coloured quilted blanket.

Meanwhile, Madonna went all bondage maid in her cheeky leather corset combo at the MTV Video Music Awards (who knew anyone still watches MTV, let alone videos...) You have to hand it to Madonna; for nearly 40 years she has radiated a self confidence that is almost other-worldly, and if she was a bloke she wouldn’t get half the stick for it that she does.

High fashion has its place, along with the headline-making red carpet outfits that only A-listers get to wear, but you do wonder what happens to all this stuff once the party is over. Stars are often loaned expensive designer dresses for high profile events, so it’s unlikely they’ll wear them again. Would you ever see the Kardashians in the same outfit twice? I doubt it.

And that is surely a dilemma in the fashion world. Sustainable fashion is on the rise, particularly among young people who are leading the way in buying and selling second-hand clothes online. And unlike most fashion trends, which come and go with the seasons, sustainability looks set to stick around. It addresses the way fashion is produced, consumed and passed on, taking into account the environment, manufacturing, working conditions, textiles, and pollution reduction. This stuff should matter - but we’ve become so used to the fast fashion dominating the high street that we’ve lost sight of the idea of buying less and buying better.

With billions of items of cheap clothing produced each year, and much of it ending up in landfill after just a few wears, the way we dress is leaving a messy carbon footprint. One study has revealed that 50 million garments are bought and worn just once every summer in the UK.

While buying better means clothes last longer, embracing sustainable fashion doesn’t have to be costly. It’s not all about the Stella McCartney vegan shoes. Many young people sell unwanted clothes online, giving them a ‘second life’ instead of binning them, and upcycling is on the rise too, with youngsters embracing the sewing skills many of our mothers and grandmothers used routinely to make and repair clothing over the years. My mum made our clothes, her sewing machine was always on the go, and she loved a jumble sale too. Most of my childhood clothes were home-made or secondhand, which isn’t as Orphan Annie as it sounds. It was quite normal back then for clothes to be passed down in families, or to friends for their kids. The online buying and selling trend, often via apps specialising in ‘pre-loved’ and vintage clothes, is just a new way of doing that. And many charity shops have some great clothing finds, largely thanks to lockdown clear-outs.

High street retailers need to wake up to sustainable fashion, or risk falling out of style with new generations of shoppers.
