don't worry it's simple, I'll teach you
The first thing you will do is open medibang, then click on file and open, then look for the game folder and open ¨www¨ then to ¨Img¨ and finally you look for a file called ¨Pictures¨ and look for the image called ¨ stand-Heroine-Cloth2¨ when you open it you can modify it to your liking, to put the clothes you want (in this case what I put on it) you have to open a layer above the clothes, erase the old clothes and put the new ones , make sure that it has to be in PNG so that it does not get damaged (do not worry, the data will not be damaged or anything like that)
