I agree. I don't think she replaced Crystal either. That's why I put "quotes" around the word, "replaced," earlier. (People have been saying that she "replaced" Kris/Crystal. Kris/Crystal wasn't even in Gold and Silver...Ooooh...Idea for next comic in sig...)
But yeah, the shirts are a little similar. I'm glad they didn't give her another mini skirt. Seriously, if you're a girl going into two regions, having two male rivals, you need to use FLY, and Team Rocket is there... a skirt is not good for traveling purposes. Skorts on the other hand...a little better, but the shorts on the overalls are good for Johto. The hat is there to block the sun out of her eyes. The longer sleeve shirt and the long socks are better for the Ice Cave. (or whatever the cave is called.)
