This, pretty much.
Also, the out-of-suit outfits of riders are usually high-fashion too (I recommend checking out the tumblr tokukei, if you're interested in that... yes, even Eiji's clothing style has a particular name). Also, that's why rings didn't seem so weird: Rider actors usually have tons of accessory and especially all kinds of jewellry. There's only few who don't wear rings and necklaces. It mirrors pretty well how Japanese males like to dress, so I don't think it would be a problem for boys to have a show about that. I think a fashion theme should work very well in Japan, as long as Toei and Bandai make some cool toys and a decent show out of it.

If Toei and Bandai are smart, assuming this rumor ends up being totally true, then the rider would have a completely different belt for each form. If it's fashion-themed, changing accessories, belt included, would make a lot of sense for each form.

Plus it's instant cash. The fanbase would be buying more than two or three belts per season. It'd be two or three belts per rider.

Was the intention to make that sound stupid? Because it sounds absolutely awesome.

Not too long ago (about a week or so) there was an image of a copyright entry for a 'Kamen Rider Layered(仮面ライダーレイヤード)' which seems to fit the whole fashion rumor.
But(notice how I am bolding this), seems like it is fake because the so-called copyright code in the image cannot be found when looked up on the site that deals with such things.
If they can pull off fruits and locks I am sure Bandai can pull off clothes hangers and buttons(heck, they made a henshin device out of sushi and burgers), but for now I will wait.

Yeah don't forget the whole Local Hero fiasco last year, guys.

What was the local hero fiasco from last year?

Jefusion mistaking local Japanese heroes/cosplayers for the new Kamen Rider and building a whole story around them which all turned out fake, non-surprisingly.

I'm amazed that people still trust JEFusion as a "News" source after that whole debacle.

Seriously guys last year Jefusion thought Drive would be a magical painter. Until there's ACTUAL information to go off of, this is just discussion of an almost assuredly fake rumor.

And I think for Gaim's year, they thought that it'd be a CD/Breakdancing themed rider. Perfectly valid idea, but not what happened.

Le sigh.

we can still dream, right?
