I even remember something on the "Making of Rx3 Noria Cam" where Noria raids Yoma's purse and then she and Yoma mention Stylist. 

Yoma's been credited as stylist for quite a few of the BeForU releases. I can't remember which ones off the top of the head but I'm sure she's been.

Hey, maybe she's actually doing something of the sort now!

She is the stylist for Riyu in Danzai No Hana and Doberman.

Read the credits cover. I hope she is still styling for Riyu though.

I know that is old topic lol but when ppls talked Yoma in the fashion and styling thing about, well yesterday i've remarked something that i did'nt at first in the BeForU live 2007 even after like hundreds of watching lol 

In the 6 rainbow section of the show it's was Yoma who commented and described  the clothes of of each girls and after i've checked the DVD box  credits and there was Written : "Stylist: Yoma."

So she really designed stylised BeForU clothes even for the Lives too i guess.

She did the styling for Danzai No Hana too. Check the album back cover if you have got it.

Ryuko, you already mentioned that directly above hinoryu's post.
