The material I chose for the undies is 100% polyester, even if it looks like cotton. The fabric is also really elastic. Moving around and doing low, open poses is well enabled. Even with stretch I placed hidden zipper in the side seam. Our previous ones where tricot and they had rubber band inside high waist piece.
I used was regular trousers pattern for the pants. I left darts for tight fit on the hips, took out some looseness on the thights and knees and flared the legs out. Without the shin guards or leg warmers, which ever you prefer, the pants look like cropped hippie jeans. When you tuck them inside the shin part they look great!
Nothing much to say about Deidara’s belly shirts. Like every Deidara cosplayer out there and pretty much everone who have read Naruto, I wonder why he wears one. Ignoring the questionable fashion taste, the upgrade is complete!
