It's the original signature line initiated around 1995 and only lasting a couple of years.
It was made by the same maker as Polo at that time, Pietrafesa of Syracuse, NY (WPL 559?), and constructed the same as Polo of fabrics similar to Polo.
It differed in that it was a domestically made line which mimicked Purple Label styling - extended padded shoulders, etc. It may have been slightly more expensive than similar Polo items. A typical suit may have been circa $800 in '96.
The white interior pocket production tag should indicate the date of manufacture in a 6 digit number, such as 960410 for April 10, 1996, somewhere on the bottom line. The 'CUT' number should begin with 'R' and there will be an 'F#' or 'S#' indicating the season (Fall, Spring) and year, in a single digit, for which it was made ('F6') somewhere in the production nomenclature.
The label proffered Chester Barrie RLPL ($1500 up) suit styling at near Polo pricing. There was also a golf line using the label, with such things as black nylon anoraks at $495 in mid '90s dollars.
You be the judge, in retrospect, as to the perspicacity of the confusing strategery.
