From 3.5 billion Reddit comments

I was on amazon looking for Korosensei Propaganda heres His uniform is a bit plasticky but silky and his tie isnt the best but if you take off his clothes o///o its very nice fabric and stuffed very well. (Theres two options , A small korosensei with just tentacles and this baby. I Got the largest one :)

Well I've found this but it doesn't have the two different colours really going for it. And this which does have two different colours but again its completely different (plus I have never heard of the website).

I think the way to go is find a long sleeve one and just have the sleeves rolled up.

teehee here his clothes are a bit plasticky but everything else is perfect about him :) (his uniform looks really cute on my dog though :)

I got it from Amazon https://www.amazon.com/-/es/Cartel-Asesinato-juguetes-oficial-ge67041/dp/B01GQ1T0T8 But apparently they're out of stock at the moment. Or at least for me. But 8t did cost only like 12 13 bucks.
