^______^ There totally are! And Zack is probably going to get in on the "convince the Brooding Threesome that black leather really isn't the best supporter of cheerfulness and sunshine and frolicking with puppies" action too, though he's sneaky enough to claim the Good Cop role:
Zack: "look, Leon, if I can convince her not to put you in the teal blue teadress with the sparkly shoes, I'll see if I can get you guys some blue jeans and a T-shirt instead" Leon: "...♥"
And then Zack carefully doesn't mention that most of his T-shirts involve Shiny Happy People lyrics or Python quotes on really wacky colors...
Cloud probably gets the Don't Worry Be Happy shirt, Leon gets the stylized angel wings shirt, and Seph gets the kitten-being-chased-by-a-stuffed-Domo-kun shirt. XDDDD
(Seph: "...is that a graham cracker? With fangs?" Zack: *too busy laughing to answer* Seph: "Fangs are good." *puts shirt on* Tohru: "Kittyyyyyyy~!")
