Well you are looking for combed ringspun cotton. Pignemt dyed shirts will give you the vintage look you are considering. I think Chouinard (or something close to that) makes some nice ones in quite a few colors. Another option is that some manufactures actually do "vintage washed" shirts. Bare apparel, continental apparel, and alternative apparel come immediately to mind. The only way to tell for sure is to order some and check for yourself. The best is very subjective in these cases.
