My Van Heusen's seem to be a lot more durable than the others, they are just getting a slightly pink hue to them. They are only washed with other whites in bleach too.

Forsyth shirts seem to be doing pretty well, except they don't have the button hole stitching around where the wings go, so they are wearing out a little there.

The "Uniform Group" shirts sold on the Lion website are terrible. If you do so much as look at them with a funny eye they will wrinkle up and an iron doesn't do much to flatten it.
