We can all admit that Sofia is one of the most beautiful women in the world.
What is interesting, is the recent trend in "loose" eyebrows.
Eyebrow design can be "tight" or "loose". Tight brows have very sharp, defined edges, are often heavily penciled or powdered. There are no strays to speak of and the look is uber-groomed.
A loose brow still has shape, but is not artificially defined, it flows more with the natural shape of the brow. There is no severe definition and much less maintenance.
Sofia, along with may other celebs this season, are sporting the looser brow. Although this brow is not as defined, it is never sloppy, just...loose!
