Just north of Disneyland on harbor (same street as disneyland). You would go north on Harbor, pass over the freeway, and it's on the right. It's been a while since I've been there. If I remember correctly its it off of orangethrope, if not it's the street before orangethorpe. It's called Character wearhouse.
it's a couple of miles north of Disneyland. You will pass Ball, lincoln, la palma then the 91 freeway, it should be at or before the next big street which is orangethorpe.
