how u knew its not in islam and not required?who has told this rubbish?
as far as a woman is concerned in islam her body full is 'OWRATH'(MUST BE COVERED)include her hair and nail.while prayer only she can avoid to cover her face and hand.its not traditional system like u said.and nobody compel to wear this,because if she want to follow the prophet words and if she want to gain heaven then they must obey islamic concepts.
