In this picture you can see that the fancy shirt is covering the leather sleeves this character is wearing. And in his pack is another fancy shirt, just a different color.
I switch the fancy shirts out, and as you can see, this color, for some reason, does not cover the leather sleeves.
I think these were made with BOD reward cloth, but im not 100% sure on that. Im 90% sure that the second pic is BOD reward cloth cuse its the same color as the tailor bods.. the 1st one, im unsure if its bod reward cloth or not
