Dragging Blue behind you, it is easy to get backstage and sign up for the Contest. There was no fee for entering, few enough took the time to partake in contests and there was only a payout, here at the local level anyway, on victory. So they were allowed in, Blue registering River as her choice of Pokemon for much the same reason you were picking Vivi for this. Here they'd find out some additional information, namely that most contests focused on a particular type of move, Cool, Tough, Beauty, Smart or Cute, which their Pokedexes helpfully listed what each move was tied to. This contest hall though? This one did a mix, with the particular focus changing at random between rounds, rather than focus on a single type.
Entering back stage they'd be the first trainers to sign up for the next set, though two more were sure to come soon. For now they were left to pick through outfits and props. None were particularly pricy, though your instincts would still likely wander if any of this could be easily stolen. Blue for her part picked through the outfits, humming as she considered. "What do you think, something blue and frilly to match River some or enhance myself to grab the judge's attention?"
