I didn't get crowns b/c of the bug, but was able to preview items. All the costumes alter the face of my character (making him way uglier). For this reason alone I wouldn't buy any costumes even if they were awesome.
But, they are not awesome. With all the assets you guys have in the game I was really disappointed in the way some of these were put together. There are much cooler looks you could have gone with for almost every single costume you put on there in the bundles, including color choices in some cases. If you want to sell a lot of this stuff I would recommend more focus on how good they look in addition to making sure they don't change a character's existing appearance designs.
