I think in arranged marriages, men usually go for beauty over brains whereas women go for financial stability over beauty. Whereas in love marriages, neither matter.

Beauty can be enhanced with some grooming or a lot of grooming, depending on what the man likes. The entire personality can change with some posture exercises, good skincare routine, good make up skills and an effort in how she carries herself. But enhancing the ‘brain’ part is more of a challenge.
