A shawl-collar cardigan is not a spare layer for when the weather turns. Worn correctly, it replaces a jacket, a blazer, or a coat outright. The Bruce is knitted at 8-ply, the heaviest weight Billie Todd makes, which means it holds its shape, drapes rather than clings, and does the actual job of outerwear instead of just approximating it. The shawl collar leaves more of the neckline open than a crewneck, so what goes underneath does real visual work. Three options cover most occasions.
The Sweater: For Off-Duty Layering
The Earnest underneath is the relaxed option. It's a lighter 2-ply crewneck framed by the Bruce's 8-ply, built for a weekend with nowhere particular to be. The weight difference reads visually, a lighter tone framed by a heavier one, rather than two pieces competing for attention.
The Dress Shirt: For Daytime to Evening
The classic pairing, and still the most versatile. A collar peeking out at the shawl neckline is the look most people picture first, and it moves easily from daytime to evening depending on the trouser. This is the version for people arriving at your door, not the version for answering it in sweatpants.
The White Tee: The McQueen Pairing
The modern option, though it is not really new. Steve McQueen wore his shawl-collar cardigan over a plain tee in the 1960s, and the pairing still reads the same way today. Plain cotton under heavy cashmere reads as deliberate rather than lazy: humble fabric against a luxury one, undone on purpose. It's also the pairing most likely to actually get worn on a regular Tuesday, which counts for something.
Why It Works With All Three
The versatility isn't a styling trick. It's a function of the weight. The Bruce is knitted in Hawick on flatbed machines from Todd and Duncan cashmere spun in Kinross with Loch Leven water, then finished in the River Teviot. Eight plies of Grade A fiber is a heavier construction than almost anything else in cashmere knitwear, which is why it moves from a sweater to a dress shirt to a plain tee without looking wrong under any of them.

Frequently Asked Questions
What do you wear under a shawl-collar cardigan?
A sweater, a dress shirt, or a plain tee all work, depending on the occasion. A lighter cashmere crewneck like the Earnest gives a relaxed, weekend look. A dress shirt is the most classic and versatile pairing. A plain white tee is the most modern pairing, popularized by Steve McQueen in the 1960s: humble cotton against luxury cashmere reads as deliberate rather than careless.
Is a shawl-collar cardigan too formal for everyday wear?
No. The shawl collar reads more relaxed than a blazer lapel, which is what makes it work across more occasions. The Bruce moves from weekend wear to evening wear depending on what's underneath it, not what it is.
How heavy is an 8-ply cashmere cardigan?
8-ply is the heaviest standard cashmere weight. The Bruce is knitted from eight plies of 15.5 micron Todd and Duncan yarn, which gives it enough structure to function as outerwear rather than an indoor layer.
Can you wear a shawl-collar cardigan instead of a jacket?
Yes, on mild days. The weight and structure of an 8-ply cashmere cardigan like the Bruce lets it stand in for a soft jacket. On colder days, it works underneath a wool overcoat instead.
What's the difference between a shawl collar cardigan and a regular cardigan?
A shawl collar cardigan has a continuous, unnotched collar that wraps from the back of the neck down to the button placket, rather than a separate collar and lapel. It sits closer to a robe or a smoking jacket in silhouette, which is why it reads dressier than a standard crewneck cardigan even at the same weight.
Can you wear a cashmere shawl-collar cardigan in warm weather?
An 8-ply weight like the Bruce is built for cold weather. It's the heaviest construction Billie Todd makes. It can be used during transitional weather. For warmer climates, a lighter 2-ply or 4-ply cashmere piece will layer more comfortably.
How do you care for an 8-ply cashmere cardigan?
Hand wash in cool water, lay flat to dry, and store folded rather than hung to preserve the shoulder shape. Full care guidance is in How to Care for Cashmere .
Did Steve McQueen wear a shawl-collar cardigan?
Yes. Steve McQueen was known for wearing a shawl-collar cardigan over a plain tee in the 1960s, a pairing that helped popularize the style beyond its original use as an under-jacket layer. The same pairing, heavy cashmere over plain cotton, still works today.
