[I can't log on-- I'm somehow wearing my whole inventory-- How can I take it off if I can't log on??]

I have no idea why sl decided to make me wear my entire inventory last night when I tried to wear an already existing outfit.  But it did.  And the sheer volume of it, I'm guessing, made me crash.  Now I can't log back on to take it off!!  How can I get logged back on?
