Most gijinkas cute? Honestly, I beg to differ. A lot of them are, yes, but.. After looking up so many (Believe me, I do. Mostly for inspiration for my own gijinkas~), I can definitely tell you there's a LOT that aren't cute. (Though I think that might be subject to argument on some of them.. XD)
One thing I suggest is to just search up a few on Deviant Art. There's a LOT of 'em there~ Or, instead there's always the option of making a design yourself. It's.. A little difficult and time-consuming, but it's nice to make your own idea, especially if you can't find any online that you like.
(By the way, if you are cosplaying a gijinka and you find a design on dA.. I very much suggest you ask the artist's permission first, cause a LOT of gijinkas are characters people have, and they MAAAAAY not exactly like it if someone just takes the design without asking.)
Good luck, by the way! Gijinka cosplays are fun, but REALLY hard to do. I'm working on one of
Mienshao right now XD
(I may search up a few to see if there's any I can suggest, but I just got up (...Yes, at 11 PM. I AM PRACTICALLY NOCTURNAL XD) and my brain's slightly muddled and can only handle typing stuff up at this point. If I end up looking up some, I'll probably edit this post.)
