Halloween stores in San Diego / alien costume

[CALL AAA]

I'm looking for some big Halloween/costume stores in San Diego.
And at those stores, I'm looking for kids' alien costumes, specifically the classic "gray" costumes. I have found a lot of aliens in capes or other TVish clothing. But I am looking for something to make a kid look like this

I have never seen the body part of that costume, but now I'm finding that no one carries these masks, either.
If anyone sees any masks like this in San Diego, please let me know.
Thanks,
Tony

I can't really say what I'm up to. It's part of a pretty crazy Halloween party. (well, the party won't be that crazy, but the plan is WAY out there)
But I will definitely post pics when it's over. And I do have permission from the kids' parents.

By the way, I have been to the stores in Poway (Poway Rd and Pomerado Rd) and the one in Carmel Mountain (by Bev Mo)
