on the sleeveless T-shirt posted by ice-boy Dec 22nd I also see a 20mm vertex resolution and a body which is mainly diagonal tris, with some zigzag as well at the chest. Both make cotton weave behavior as intended for this T-shirt I hope, but the zigzag chest will behave different from the diagonal part, as in high vs low quality cloth.

My major concern however are the increasing vertex densities around the sleeves and toward the neck area. In contradiction to what one might believe, higher density does not mean: more solid behavior. Instead, higher density means: thinner cloth and more elasticity (unstable, bouncing, wobbling).

My advice: make it uniform, and if you can, preferably zigzag all over. If you want it to behave a bit thicker than dish-cloth or rag as for a high quality T-shirt, then you'd better lower (as in: halve or quarter) the mesh density. Then, by bringing down Fold- as well as Shear resistance to 0.5, you can do your girl-in-a-wet-Tshirt shot, even animated.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
