The same was done with the arms (st2.22 & st2.23), it was proving difficult to clean up any unwanted marks etc under the arms and the same with the folds and creases in the sleeves (clothing is i think one of the hardest things to sculpt - there is a product called 'Paverpol' which when applied to cloth with say creases in it make the cloth set hard, this could be an easier and more realistic way of portraying clothes but then you got make the clothes so i'm not sure…and i cant sew).
