25 of The Best Marks and Spencer Workwear Buys

last updated 16 February 2023

It’s the first week of January, which means many of us are mentally and sartorially preparing to head back into the office. That’s right, in addition to pulling ourselves out of the Christmas switch-off, we also have to start the transition from wearing festive PJs and super-soft loungewear 24/7 to donning office-appropriate attire.

The new year is all about fresh starts, so you might find yourself wading through your tired workwear wardrobe and feeling the urge to add some newness into the mix. Luckily, you don’t have to splurge to change things up, or update your workwear capsule wardrobe, because I’ve identified an affordable brand that’s covered all the bases.

M&S insider Sam Briones wears a double-breasted blazer, white tapered trousers and black loafers from the high-street brand.

I won't lie—I largely overlooked Marks and Spencer until quite recently. It took a few nudges from friends (who mainly recommended its denim offering) for me to finally realise the value in ’ fuss-free, timeless and well-made clothing. And these qualities are especially crucial if you're seeking smart pieces and quality tailoring without an intimidating price tag attached.

For work, you want your outfit to be smart, practical and professional, and M&S ticks all of these boxes. Plus, the high street hero isn’t afraid to back the trends, so if you’re someone who likes bringing their fashion sense into the office, you’ll be well taken care of.

But don't take my word for it; keep scrolling to see and shop our edit of versatile workwear pieces you can start wearing tomorrow.
