Note wholesale prices averaging $26.25 in 1984 on primarily Japanese woven Threadtex (TTX) tartanish fabrics. That would have been circa $55 retail.
There've gotta be beaucoup
original NOS Gitmans out there languishing in the musty, dusty stock rooms of old traditional retailers or hanging unwanted from Pater's estate in almost pristine condition on Goodwill racks.
Gitman did not use MOP. They used a chalky white looking faux horn button on dress shirts. In the '80s Gitman was so popular that Lands' End, Kenneth Gordon, Nantucket Shirts, Norman Shirts and others copied the double track stitching at he the collar edge and the aforementioned buttons. At the time Gitman shirts incorporated more stitches per inch on the front plackets, collars and yokes than competitive shirts. It's been a while but the last I looked that was not the case. Oddly, vintage Gitman shirts had double-needle side and sleeve seams that weren't particularly impressive.
For the thrifters: The brand 'Bert Pulitzer' preceded 'Gitman Bros.' as basically the same shirt before the early '80s. That's not to be confused with later B.P. shirts which were out of B.P.'s control. Gitman made Paul Stuart's basic shirts for years. Also Sak's private label. If you see a private label shirt with double track stitching on the collar edge, chalky white buttons, and collar band label as below, either in white on green or vice versa, it's Gitman. Obviously, sport shirts had tortoise-like faux horn buttons.
RN number for Ashland Shirt Co. is RN55760 (probably on old Bert Pulitzer)
RN number for most vintage, with a small v, Gitman Bros. shirts was/is RN63620
They're the same source. The RN# on these shirts can be found on the lower front center beneath the placket, unless that's changed.
