Castle on the Coast (UP)

Below is a list of each costume, how much they cost, and where to find them.
Kudos to psnprofiles for the only comprehensive list I could find.

1. Retro George - Free - In the secret ocean area underwater. See the "All Blue" achievement for how to access the area.



2. Diver George - 170 - Underwater in the intro area in a 'church' like building.
3. Solid mammal - 170 - Top of the library area inside the castle.
4. Some Kid - 170 - Take a right into the first room you can enter once you enter the castle.
5. Georgalf the Wise - 170 - Upon entering the Forest area, wall jump up above the entryway.
6. Roarr! - 170 - In the Blue Key area, up on top of a crumbling castle section near a rotating fire wheel trap.
7. Vendrick - 170 - Can be found through a set of blue doors near the stained glass portal.
8. Aleandra - 170 - On top of the entryway upon entering the Stunt Park area.
9. Sir Georgy - 170 - In the Rainy Cathedral area, very hard to miss if you're making your way through the level. It is in a room with an orb on a swinging platform.
10. Optimus George - 1000 - In the interdimensional hub area, on a platform to the right of the underwater and castle portals.

If you are having trouble locating these costumes, the psnprofiles link includes images, but there is also a compass in the bottom left of the screen. The compass will always point to any stars you've yet to collect, then any clothes you've yet to buy, then any petals left in the area.

Good luck have fun!
