This is my "We Are Not Amused" design as it was photographed originally back on November 16th:

Here is what the exact same shirt looks like if I wear it today:

This warping effect is now happening to all shirt designs when I wear the shirts on this avatar. If I send the shirts to my female alt (I use for modeling purposes) they look normal.
I have no idea what is causing this, but it's really getting annoying. I've tried "resetting" my avatar - wearing a "New Shape", "New Skin", "New Eyes" and "New Hair". But when I
put the normal outfit back on this warp effect is still happening on my shirts.
I have never seen this kind of thing before, not in five years of making t-shirts, both on SL and OpenSim. Has anyone else ever run into this? Any ideas on how to fix the problem?
