Depends how you want to wear it, but I don't think it'll be much of a problem. I haven't done it, 'cause I don't pack daily since I'm not out at school. But I suppose you could wear girls undies with whatever sanitaries you use. Then in front of that you stick the packer, I wear mine in a sock, so, you stick it in a sock and then you pin it to your undies. Either your girls undies or the guys undies you'll wear over it. Should do the trick.
