Do not enter EX mode yet. Talk to the costume woman and agree to
help her. You will require the item that allows you to leave the
maze in order to do this. Talk to the old man to start EX mode.
There are various fabrics that you must find in the EX mode levels.
Take them back to the costume woman to get a new costume. Each
character has three different alternate costumes that can be found,
based on Street Fighter and Vampire Savior. To get the final costume
for each character, defeat the Boss on level 100 in EX mode.
