They are actually Disney Polynesian or Hawaiian outfits from a couple of years ago.
We collected a set using EBAY mostly so we could all match for the portraits.
But every year Disney usually releases a new Hawaiian style set of clothes for the family.
Thanks!
There's a couple more like this.
On Sunset Blvd if you are lucky, you can get Lilo, Mickey, or Minnie on some benches.
This one was done near the Sorcerer's Hat.
