I don't Marielx was talking about 2d clothing, you have to consider that she does not wear "classic" clothing but instead 3d clothing as seen here >>2015832.
>Gimp
I will never recommend Gimp for the reason that its a rip-off Photoshop and hard to use. You are free to use Photoshop or Paint.net for simplicity's sake.
