Hi ,
You put on an outfit, look in the mirror and decide something is not right.
You change your top, try another pair of trousers or switch your shoes. Somehow, you are still not satisfied.
Sometimes, changing is the right decision. Other times, you are trying to solve a problem you cannot quite identify.
Perhaps the trousers do not work well with your proportions. Maybe the top ends at a point that makes the outfit feel unbalanced. It could even be that the individual pieces work well, but not together.
