how to make a hud for changing textures of the mesh clothes

[Rolig Loon]

Assuming that your textures are properly UV mapped to match the mesh clothing models that you want to apply them to, that should be a fairly easy script for someone to write.  If you are a scripter, start with something very simple like http://wiki.secondlife.com/wiki/LlSetTexture#Examples or (better) the equivalent with llSetLinkPrimitiveParams and add it to a basic menu script like https://community.secondlife.com/t5/LSL-Library/A-Simple-MultiPage-Dialog-Menu-System/m-p/2126747 .  If you're not a scripter, post in the InWorld Employment forum to hire someone.
