Frank is a good basic watchcap-style beanie; the warm tweed yarn really makes the hat!
It’s a structural sibling to my other hat, Driggs, but a little less absurdist, so you can knit one for yourself if you are a serious person with serious business to attend. Professional in a cold winter city? Knit this up in the luxury yarn substitute for the one I used (Queensland Collection Kathmandu=Jo Sharp Silk Road) for a warm, presentable topper.
Wear it with the brim folded for a classic watchcap look; wear it flat (this works at least for smaller sizes) and slouch it slightly for a look that is more casual and modern.
(There’s no reason why you can’t knit and wear Driggs as well, but it has a different effect when paired with the business casual ensemble I’m imagining.)
