The garment used for this tutorial is:  Full Perm Rigged Mesh Ladies Knotted T-shirt (Click here)

Test Fit the Mesh

Initially the t-shirt looks fine, but on closer inspection, you will see a bit of skin poking through on the bottom of the arm.  Use camera controls to view from all angles.  Let your avatar move freely, with your AO on, watching for more problem areas.

Wear the Alpha Mask and the Mesh Garments.  Zoom in and notice the lines from the SLUV Top showing through where the body pokes through the garment.  Using the lines, try to identify the area that is to blame.  In this case, note the pink area just below the sleeve.  Use it to estimate where the Alpha Mask needs to be trimmed away.

Trim away the alpha mask to just a little above that line.
