about classic tight jerseys with short shorts

Hey guys. Is there any way to make regular teams use those tight jerseys and short shorts (like 60's Celtics for instance), either renaming some files ("cloth_blablabla" and stuff) or even with roster editor? thanks a lot

right now the only way to do it is to change the classic celtics and other tight uni uniforms to the modern teams in the roster editor

to change existing uniforms to the tight ones, you need to wait for the reditor, changing file names does nothing
