The shirt in question. Black is easier to see.
Half naked sim, half shirt in question.
Edited with lines to show the clear difference between the edges on the abs and the bottom of the sim's pecs.
Naked side view. Take note of how far the chest protrudes.
Side view with the shirt. Pecs are displaced back and up.
