Jennifer Lopez showed off two drastically different looks yesterday -- but which one do you like better?

First, she gave fans a good glimpse at her famous curves in a white cut-out dress accentuating her hips -- showing them off, uncovered, at 106 & Park on BET in NYC.

Later than night, she jetted to Hollywood and switched from white to all-black by wearing a tight leather vest, pants and boots.

Check out more of the two looks in the gallery, then let us know ...
