I really liked Brendan's Emerald design but this one is awesome too, looks like something a real kid would wear. Happy Pokemon has started to finally catch up with modern styles, they've been lagging behind. Cannot wait until these games are finally released!
By the way: I love their new outfits! They are still in this old pokemon-style you know? Not like the outfits in pokemon x y. I think this game was a way to modern. This is why I'm so excited about the remake!
