The occasion: If the occasion or the place that is being attended is a formal one like an office or a meeting, the clothes will be greatly different for these occasions from the ones that are worn to casual occasions and gatherings and places like a friend's house or a party or anything other than a formal place or occasion. Another thing that greatly determines clothing is the fashion that is currently going around.
