Aphrodite's Blessing is usually classified as the claiming of a child of Aphrodite.

The Blessing:

Piper McLean, the only child of Aphrodite that is seen being blessed by Aphrodite in the series.
On Aphrodite's children, the demigod is enveloped in a thick, pale red haze, and when it clears, the demigod's hair, face, clothes, etc. becomes perfect. No matter how the demigod tries to mess up his/her appearance, it automatically becomes perfect again. The blessing lasts anywhere from a day to a few weeks. When girls get the blessing, she will go under a pink haze and will then look the way that Aphrodite thinks would be the most glamorous. Her hair and makeup will be automatically done to perfection and her old clothes will be swapped with a new fashionable outfit, shoes, and accessories. Like said above, the blessing can last a day or two but, if she's really lucky (or unlucky in Piper's case), Aphrodite will keep it going for at least a week. No matter how much they mess up their hair, wash the make-up off or cry, they will remain gorgeous. However, the blessing does allow you to change clothing.
It is unknown how the blessing effects sons of Aphrodite, but it can be assumed they get a new set of clothes and a new hair style like the girls.

It is unknown if the children of Venus go though this or if she claims them differently
