Every couple of years, Vogue does a feature on the return of the bold brow. You could set a watch by it. I have never been inspired by these features, partly because everything in Vogue sounds like Plum Sykes wrote it and partly because bold brows are never, ever out of fashion.
As with a strong jawline, thick brows are one of those hallmarks of masculine beauty that happens to look equally good on a woman. If masculine/feminine traits exist along a spectrum, then my beauty idols are all clustered along the same specific region: Charlotte Rampling, Audrey Hepburn, Lauren Bacall, Brooke Shields, Jacqueline Onassis, Carine Roitfeld….they all have blunt jaws and thick brows. It's a classic look.
You can't will yourself a strong jaw, but anyone with access to a brown-ish pencil can have big brows. The thicker the better! My ideal woman looks exactly like Tom Selleck, but without the mustache. In her beauty book, the late great Arlene Dahl recommends using a "colorless mustache wax" to tame unruly brows—if you've tried this, please report back. I've had good luck with clear mascara (Maybelline Great Lash). Sometimes, I make mine darker with Diorshow Mascara in Chestnut. I like using brown mascara instead of a brow pencil because my brows are already thick and do not benefit from the illusion of further thickening. For occasional stray hairs, I rely on the Revlon True Precision Tweezer. This is not something you can keep around the house if you have children—it is pointy. Also, it is made in Germany, where they take precision seriously.
If you're looking to transform yourself for the New Year, giving yourself a vigorous brow could be just the trick. A new you? This MIT study found that eyebrows were more crucial than eyes in face recognition. The transformative possibilities are endless!
The same study also featured an illustration, which I would like to present, in conclusion, without comment:
