Anyone know how to make 80's Legends wear 60's shorts?

I need to know how to edit the 80's legends like Bird, Magic, etc... using DBF pro or some other software you may recommend me, so that I can give them shorter shorts like Stockton's to give them a younger appeal in their days. In addition to that, can you edit their build and hairstyle too, I really want to give Bird longer hair like he did before.
