Vintage Style vest / singlets...

Looking for a source of vintage style vest / singlet...(not the string variety)

Pike Bros were selling some nice ones but this years version are hideous IMHO with a deep square neckline making them like something a circus strongman would wear on a bad night.

I'd check for the usual suspects in WW2 reenactment (ATF, WPG, SOF...), most of them carry white and OD vest.
