he's wearing a black thing around his head (like a cloth mask i think. so u only see the short hair on the top not the hair on the back of his head) and then the orange mask.
well from here you can see he also has black gloves, and his coat has a big thing that goes up. its not a hood but well. u know. its in the pic. u can also tell what shoes(google akatsuki shoes if you cant tell too well) socks and pants he wears from this pic. his toenails are painted a dark purple. every akatsuki paints their nails that color.
this is tobi's ring. if ur into getting contacts for your first cosplay (highly doubt u r since its ur first but well just in case) notice the type of sharingan they are and look for a legit site that sells em and get a prescription or whatever its called. and yeah bada beep bada boop bada boom. i think i got to all of it.
also, when collecting things to get ur cosplay together, KEEP REFERENCE PICTURES!!! its a lifesaver. ull never forget something if you have em and they always show you what your aiming to look like. hope u have fun with putting ur first cos. together!!!
