Answer 1

Use .get().reverse() See Help

$.each('#men_shirt ul li').get().reverse(),function(i)//use get.reverse method()
{
   var iid=$(this).attr('id'); 
   alert("sdfsdf"+iid);
});

You can extend jQuery with the reverse method:

jQuery.fn.reverse = [].reverse;

And then:

$('#men_shirt ul li').reverse().each(function() {
    ...
});
