With spring dressing in full swing, this season is all about layers, and a tank top is a great option for those in-between days. Princess Catherine was just spotted in a gorgeous, versatile brown option that is bang on trend for the season.

Last week, the Prince and Princess of Wales visited IntoUniversity, a charity they supported through their 2011 Wedding Gift Fund. Catherine, 44, stepped out in a sleek brown cashmere tank from British label Me+Em – a brand she has been leaning into heavily this year. Worn simply on its own, the sleeveless knit felt modern, understated and quietly polished, striking that balance Catherine does so well between relaxed and refined.

It’s one of those pieces that works hard without trying too hard - perfect worn solo on milder days, or layered under a crisp shirt or blazer when the temperature dips. The rich chocolate tone adds warmth to spring dressing, while the clean, sleeveless cut keeps it from being too heavy.

If you’re looking to invest, Catherine’s exact piece is still available at £195, though it’s already starting to sell out. Smaller sizes are currently more readily available in a soft pink colourway, which offers a slightly lighter take on the look.

But if you love the aesthetic and want something a little more accessible, we’ve tracked down a high street alternative that delivers a very similar feel for less.

This Jigsaw tank, priced at £125, taps into the same minimalist, elevated vibe. Made from cashmere in a near-identical brown tone, it mirrors that clean, sleeveless silhouette that makes Catherine’s version so wearable.

There are a few subtle differences that actually work in its favour. The Jigsaw design features a slightly more defined ribbed trim at the neckline and hem, which adds a touch of texture and structure compared to Catherine’s smoother finish. The fit also leans a little more relaxed through the body, giving it an easier, more laid-back feel for everyday styling.

Available in sizes XS to XL, it also comes in a chic dusky pink if you’re after something softer for spring.

Ultimately, it’s the kind of piece you’ll reach for again and again, whether styled with tailored trousers for a smarter look or thrown on with denim for something more off-duty. And that’s exactly why it works so well – simple, versatile, and quietly on trend.
