well chowdary I appreciate ur effort to know abt Islam. Men do have restrictions in wearing clothes. I just want to make it as simple as this....Imagine a girl standing beside you with short clothes or not in burqa ,,for a minute u will have a glance at her and something will go in our corrupted mind...and she may be anyone...but if a girl is there in burqa atleast we will not think of her because we cannot see and imagine abt her beauty.....
