And then part of the game has you infiltrating a Team Flare base, dressed in their outfit.
I mean the game even mentions buying the outfit. its disappointing you can't wear it. It's so fashionable!
Similar to Platinum's storyline where you infiltrate Team Galactic or Team Rocket in HG?SS
No, because you don't "fake" join either of those teams. If you did this, Team flare would think you are part of them. The part of teh game would have you go deep into a team flare base, possibly steal an item, then an admin catches you, and then you have to fight a bunch of team flare members to escape.

So, kind of like what you did with Team Rocket in Poke Heartgold/Soulsilver before Silver blew your cover? I do agree that they should let you get the suit and sunglasses in the costume shop, though. Also, why can't you use the grunts/admins/scientists/boss in the PSS icons? They let you use the champion, Elite 4, and gym leaders, so why not them?
