From the lapel width and shoulders, appears to be late '90s by Pietrafesa* of Syracuse, NY (defunct). If it is, it should have a production tag in the left lining pocket that will have an exact date of manufacture on the bottom (example 980529), however some just had a season and year (F8, S8). Pietrafesa's WPL5596. If the aforementioned is confirmed, and the jacket has side vents, at the time it was called "Polo Traditional I". Excepting the flat front fad of the last half dozen years most Polo suit trousers were historically forward pleated. The quality diminished in later years. If small hand sewn threads are not easily evident along the shoulder seams of the lining it is of the later period. If the rectangle on the label is not really a rectangle (the upper right has a 45 degree slant instead of a 90 degree angle), it was made for discount sale.
Contrary to the above, the top buttonhole appears finished on the inside to facilitate a 3-2 roll lapel with a neatly finished top buttonhole showing in the roll. Some of the later USA made 3-button fronts, and the Cornelaini, seldom have this feature - they're finished on the outside.
*In addition to Polo, Pietrafesa made private label suits for Brooks Brothers, Nordstroms, probably SAKS and numerous others with varying degrees of quality. Their own brand was Ledbury Ltd.
One reserves the right to be mistaken.
