Ruling on putting a zipper on a woman’s dress
Question

                Is it permissible to put a zip on any part of a woman’s wear; on the back, the side, or on the chest?.
Praise be to Allah.
    There is nothing wrong with putting a zipper on a woman’s 
    dress, and there is no limit to where it may be placed on the dress. It 
    depends on where you think is best for it and what is concealing. End
