Hi Dweia,
Now that you have your texture uploaded by following the steps in the previous posts you'll want to apply it to the clothing item itself.
Make sure you are not wearing the target type of clothing you want to make. This isn't really required but it makes finding a menu button easier later on.
Go into 'change appearance' on the pie menue (right click on your AV).
In the apperance editor, select the item of clothing you want to edit 'shirt/pants/jacket/etc...' that you want your texture to go on.
Select "new 'shirt/pants/jacket/etc...'" (this should be the only thing listed if you removed the clothing item before starting the edit session)
Now you should be wearing a plain white version of the article of clothing.
NOTE: If it's an undershirt/underware layer, you might have to remove any shirt, jacket or pants worn over it in order to see it properly.
Now select the 'texture' block on the left to bring up a pulldown menu listing all the textures in your texture folder.
HINT: I made a 'textures offline' folder and moved all the textures I'm not currently interested in there. This makes the pulldown list much smaller and easier to find stuff. Simply move any files from the 'textures offline' folder back to the textures folder when you want to see them in the pulldown menu again

Also, files can be put in subfolders for organization purposes within the texture folder and the pulldown will still list them. I make a separate textures/subfolder for each build project or 'suit' of clothing and move that whole folder to 'textures offline' when I'm done for safekeeping and future refrence.
There is a 2nd block for selcting a tint color. You can use that to change the color of clothing somewhat by giving it various colors to blend with. Works best with light color clothing.
Adjust any sliders you need to for sleeve length, etc. and save the new article of clothing. (it will automaticaly save out to your 'Clothing' folder so give it a reasonable name when you save it so you can find it again
