Is light skin the universal standard of beauty?

In almost every culture, women want to be lighter, except for maybe the U.S. culture? But still a long time ago in the US people wanted to be lighter. Is lighter skin naturally more feminine? Another interesting thing I picked up on is that in almost everyone culture a woman with an hourglass or curvy figure is considered beautiful? When I say curvy, I do not mean overweight or voluptous. A women with a full round bust, narrow waist, and wide round hips that are about the same size is her bust is generally viewed as attractive regardless of cultural.
