We never thought we'd see the day that Kate Middleton and "on fleek" appeared in the same sentence, but we figure there's a first time for everything ... On Sunday, the Duchess rocked a set of bold arches that were the very definition of the viral term, while attending a service in London commemorating the 75th anniversary of the Air Training Corps. Kate has naturally full arches to begin with, but a touch of aptly-placed brow pencil or powder helped to emphasize their shape. Because everyone on the Internet just has to make a comment, Middleton's slightly more dramatic look was met with many divisive opinions over whether or not she went too far with the brow filler, though as far as we're concerned, she could make even that weird, '90s-era comma brow look good.
