The rise of GLP-1 weight-loss medications like Wegovy and Mounjaro is not only transforming dietary habits but also revolutionizing how people shop for clothes. As millions shed pounds, the apparel industry is seeing a surge in demand for new wardrobes, with consumers increasingly drawn to brighter colors and more tailored fits.
Hayley Grice, a 50-year-old from Shropshire, dropped seven sizes after starting Mounjaro two years ago. Now a UK size 12, she says, "I'm very happy with my physique right now. I would have shied away from color, but now I don't care—if I like it, I'll wear it."
In the US, where 21% of adults have tried these drugs, spending on clothing has shifted noticeably. In the UK, 5% of adults (nearly 3 million people) are currently on GLP-1s, a number expected to rise to 13% by 2027, according to PwC. The consultancy notes, "GLP-1s are creating a new consumer."
About 60% of users are women, and Mintel reports that 1 in 10 women aged 35-54 use the drugs. Spending patterns show users buy more clothes, skincare, and sports gear while cutting back on groceries and alcohol. The arrival of pill versions—like the Wegovy tablet now available in the UK—is expected to accelerate adoption.
Berenberg analysts estimate a 1% boost to the UK clothing market from GLP-1s annually for the next three years. Mid-market retailers like M&S, Next, and Zara are poised to benefit, as customers seek more structured, body-conscious silhouettes. M&S has seen 65% of jeans sales now come from sizes 6-12, up from 40% historically.
Conversely, plus-size retailers are struggling. London's BeigePlus reported a 20% sales decline over two years, calling the impact "catastrophic." Even as users buy more clothes, many opt for thrift stores or sales racks while still losing weight. Melody Ewert from Minnesota says, "I don't want to buy a whole new wardrobe until I reach my goal."
The trend also influences shapewear and beauty products, with brands launching lines to combat effects like "Ozempic face." As more people achieve significant weight loss, the ripple effects across retail are undeniable.
