You might not think that your eyebrows matter, but full, well-groomed brows make a huge difference when you want to slim down your face. They add definition and create “a triangular illusion, keeping the onlooker’s eyes on the center of the face,” Hawkins says.

This is easy to do if you have the tools (try Anastasia Best in Brow Pencil Set, $44, which comes with everything you need). Use tweezers to pluck any stray hairs below your brow only. Then use a soft pencil to fill in your brows and follow with brow powder. Set your brows with a bit of clear mascara to finish the look.
