Her shorts just look like cut-off jeans, with the things that look like Klonoa's ears being pockets. Those are worn fairly common. They are also not that short, and also worn fairly common. Seeing as they're supposed to be older, seeing a teenage, female protagonist wearing shorts like that is actually pretty typical. If you think not, go to your local high school...
As for the new Pokémon, I was hoping for something more unique, as it seems they're retreading ideas, but I guess the starters should really be the most familiar 'Mon in the game. Liking the fire starter, the grass one is meh, and I think the water one is kind of ugly, to be honest. Hoping the snake becomes grass/ground, the pig, as already mentioned quite a bit, fire/dark, and the otter water/ice.
