Perhaps the developers have a weird since of humor......
This is Japan we're talking. They can do stuff even America won't allow. Good example : anime shows with swears.
She wore a thong in the sports games whereshe had that minidress. Those are also the games where her butt jiggled on its own steam. However, i brought this up now that I saw that they're continuing this trend with Brawl. Now she even does winks when she butt bumps you. So I'm talking about Peach as a character, not just in this game. But this game is the latest, and seems to keep making her suggestive.
Well, I don't think so. I think her winking and such is a improvement. In Melee, she was merely expressionless. Everytime she did her Smash attack, tilt attack, special attack, or even taunt, her expression didn't change. The only time it did change was when you hit her.
Also, keep in mind that she wasn't wearing neither a thong or panties.
Better warn the people and make this a link, then nobody can say they accidentally saw it and are scarred for life ^^; Or PM me, that's better I think
Several women, maybe, but I doubt the guys. Would you actually be scared for life if she was wearing victoria secret undergarments?

I highly doubt it.
OK, but I hope I won't get modded because of this.. =(
WARNING! Skin showing!
After getting some feedback, I became unsure. Maybe it's not a thong after all. What do you say?

Is it a thong or just part of her dress?
In any case, her butt jiggles in those games. And in SSX, it jiggles too much. >_<
Wow....i never got those games, but I'd never expect her to be wearing a thong.
Okay, serious times.
I know it may seem like she's 'suggestive' but she really isn't IMO. She has her only weapons in her arsenal. They just give her moves that act to her personality and history of Mario games. Like her Fsmashes.
About her side B, ...yeah, I got nothing to vouch for that. XD Maybe they gave her a explosive *** because Bowser Toads, and even Luigi tried to hit that. So, she did a Full Metal Alchemist tatoo on both her *** checks and then went Roy Mustange on them.
Also, to a note to everyone, under her dress isn't a thong or panties. It's bloomers. It's what princesses such as herself wears in the old time. They must've gave her thongs in the sports game because of the mini skirt she wears (That and it's probably more comfortable then panties when playing sports. I dunno, I'm a girl XD).
Remember, she's still our sweet princess (thought she's more of a ***** in fighting gamesXD)
and Princess Peach is just as sexy as Zamus (I wished her hair was out instead of in a bun.)
