I noticed a lot of the stores at both theme parks have Disney Princess Halloween costumes for sale. Now that Halloween is a little more than a month away, almost every store has some sort of Disney Halloween costumes on display. I went inside the gift shop on the Paradise Pier across from the cartoonists and Ariel's Grotto to take some pictures of the pretty Disney princess costumes for sale for Halloween. They do have these costumes all year long, but they are usually in select stores like the Bibbbity Boppity and Enchanted Chamber by Sleeping Beauty's Castle.

The Minnie Mouse orange and purple with black polka dots and green trim costume is adorable. No picture would do it justice. I couldn't find this one available online at the Disney Store, so you're going to have to purchase one at Disneyland.
You could check eBay if you can't buy one at Disneyland. The price is going to be somewhat higher but if you really want one, I have seen them on eBay. Where there is a will there is a way! You could just admire the cuteness of this one here in the picture too.
This orange, purple, green and black polka dot Minnie Mouse Halloween costume has matching ears or hat with ears. It's totally cute. The witch hat with ears has orange and green stripes with a orange and black polka dot bow and purple lace trim around the brim. At the theme park the dress retails for $64.95.
