What kinds of clothes can you put on a obitsu doll?

I'm getting a 27 cm slim boy obitsu and i was wondering what clothes and shoes will fit them like Pullip, dollfie, barbie/ken, bobobie, or any other types of clothes/ shoes this will be my first doll and i have been looking for the right clothes for about 3 days now just under obitsu and can't really find any thing i want.. for the pants and shoes... also will the girl shoes fit the boy dolls? and the girl clothes will they fit the boys if they are slim body?|||The Ken clothes should fit them.
