Those things drove meet nuts when I was a part-time salesman at the Madison Shop of Rubenstein Brothers' in New Orleans in the early 1960's. Locker loops were a trademark of Gant shirts, most of which were sold under private label. The other big Ivy League button-down makers, Sero, Wren, Creighton and Eagle did not have the loops at first. At Rubenstein's, however, we carried the Gant label.

Locker loops were a "hot" item, but most of the teen-age girls who came in to buy shirts for their boyfriends did not know or refused to believe me when I said that that they were on all Gant shirts. Therefore, they insisted on tearing the packaging apart to make sure it was there. Poor me had to try to put them back together again.

Gant was easily recognizable by the loop; J. Press and Eagle by the pocket flap and Brooks by the absence of any pocket at all.
