When you think of heirloom gifts, you think of items like watches or blankets. But what about a cashmere sweater? Thirty years after a cashmere sweater was made that his dad passed down to him, Todd Kozan was inspired to create his brand. Billie Todd offers a luxurious collection of men's knitwear that blends classic construction with a modern sensibility.

Designed in Boston, Billie Todd produces their knitwear in Hawick, Scotland. The cashmere has a great weight to it thanks to the Scottish yarns that are produced by Todd & Duncan, the world's leading cashmere yarn spinners with over 150 years of producing soft yet strong material using sustainable production techniques. Also, “Billie” is an endearing Scottish word, meaning lifelong companion—much like the sweater you'll own for the next few decades, at least.

Polo sweaters are definitely having a moment this fall, as brands like Norse Projects, Buck Mason and Alex Mill are all offering some great options. Billie Todd just recently launched their own knit polo, which I'm already a fan of. The brand created a three-button style that's casual enough on its own or dressed up under a blazer. They employ a classic (yet often overlooked due to the additional time and yarn it requires) technique called the Milano stitch, which ensures the collar keeps its structure, even when layered. It makes for a small, but appreciated detail to this menswear staple. Personally, I can't stand when the collar of a sweater polo is flimsy and gets all bunched up whenever a jacket is over it. We caught up with the man behind the cashmere to see what he suggests pairing with the new polo.
