Today’s lunchtime buy looks to us like a modern classic in the making. With a truly flattering cut, the Penn dress from L.K. Bennett is the go-to piece worth dressing up for seasons to come.

Not to underestimate how spot on the Penn is for autumn mind, thanks to a lower hemline (calf-reaching, of course) and 60’s-inspired square neckline – Joan Holloway and the Mad Men girls would certainly approve.

Rich jewel tones like this deep purple are always winter favourites; we’re definitely classing this dress as a long-term investment. Paired with a tailored dark blazer or cropped knit, this luxury look will stand out from the crowd – just add a pair of patent peep-toes and you’re good to go.
