Please don't follow "trends", instead buy what suits u're face =) if u have a large forehead, u can wear a matha patti..if u have a small forehead chose a small tikka instead of a big one! Jhoomar can be worn regardless of the size of u're forehead..
U're hairstyle is important as well..no front "poofs" or heavily backcombed hair at the crown if u chose to wear a matha patti or teeka..
