Why do white girls tan their skin? Why why?

I don't understand why do white girls like to tan their skin. Can you explain me? I mean there are darker Caucasians who wish that they had pale skin.
For example india or southasia in general is the biggest market for skin lightening creams but on the other hand white girls are tanning themselves to look darker. LOL?
