The factors should be considered in the planning and making pockets 

Pockets are essential decorative and functional design features of most outerwear garments. They can be placed singly or in the case of some types, applied or set in, arranged in groups. In the process of planning and making pockets a number of factors

should be considered:
1. Position : The pocket must be positioned so that it can be used effectively, so consider the movement of the hand and arm and place accordingly. Also bear in mind aesthetic consideration.
2. Size: most pockets must have an opening or 'mouth' and a 'bag', so consider the size of the average hand, and also the type of contents that the pocket will contain. i.e. a handkerchief pocket need not be large but if a large quantity of coins is to be carried then the pocket must be sized accordingly.
