When wearing gloves or any other type of clothing on the clothing layers, sometimes it happens that, when not using alpha textures, the clothing texture would be shown all over the layers size. Even if you exactly saved certain f.e. pants length, glove length etc. So f.e. if you wore gloves, you would be displayed as if you wore an entire pullover out of the texture you placed in the gloves layer.
This happened with a few clothing pieces I created and sold in a bundle in my shop. A few customers reported this bug to me. It was solved in the end... but I had to make special alpha textures to fit the gloves or pants.
I experienced it myself as well, but can't duplicate it on purpose. Now f.e. everything is displayed fine on my own avatar.
If You like I can send the certain clothing pieces of which I know for sure that those were displayed falsly on a few people.
