Question: how do i make my cloths look like cloths instead of plastic?

hello,

i hope this is the wright place to ask this.

so i got a small problem which i hope to get helped with.
i just created a hoodie package. i made bassically the same hoodie but with difrent colors. now my problem is that all other colors the the default coler look like plastic. as you can see in the spoiler the black looks good evenon the picture isnt that good looking. but the blue arms are looking like plastic.

so does anyone here knows how i can make it look like fabric/cloth. i did some search on google but couldnt quiet find what i was looking for. i tried using noise filter. im using GIMP and Sims4Studio.

thanks.


Edit: i found a working way to make them look good i used a pencil and colored on it with a slighly darker color. and now it looks good.
new pictures will be added when im done.

kind regards,
Gert-Jan
