Keep in mind that Beautiful is a very subjective thing. But at least, there are some universal measures of Beauty, especially the beauty of Lips. Now look in detail at the shape of Angelina Jolie's lips.
First, look at how the size of her lips, to give proportion onto her face. Because her lips is very thick and stretchy, slightly imbalance arises on her face, or a little disproportionate. Simply put, Angelina Jolie's lips is less beautiful, because its size is too thick and stretchy. And it makes her lips is more appropriate to be categorized as a sexy and or a hot lips.
The second is about the cupid's bow (a facial feature's double curve on a human upper lip). Lines on her cupid's bow look less obvious and less curved. Where, the Curve has more aesthetic value than a flat, blurred, or straight line.
The third, her lips also looked too jutted out, as if it had been bitten by an insect.
A feature that is still looked beautiful on her lips, was her philtrum (also known as the infranasal depression, is the vertical groove in the upper lip). Its vertical groove still looked firm and look like an open brace. Yea, it seems that Angelina Jolie's lips is more appropriate to be called as Sexy, rather than Beautiful. What do You think?.
