I see RLPL are selling RTW suits/SC again. Thought they phased that out a couple of years ago, for MTM only.
But...almost 5k$ for a Sportcoat?
I can only offer comparative remarks, since I have a PRL with a similar looking label (and several others with the more recognizable Corneliani tags inside the pocket). It looks similar in format to a blue PRL blazer I have (but mine is in English, not German, and where that is light blue, mine is more grey). It otherwise looks the same, including that it looks like the label is intended to be cut (so as to separate the portion with the little boxes at the bottom). Maybe you weren't asking about this, but the "Polo by Ralph Lauren" tag on mine looks different - it doesn't say Made in Italy on the edge and instead has white (in one case blue) stitching like in a /\/\/\/\ pattern around the border. Aside from the inside pocket tag, all other tags on my jacket are the same as those with the more recognizable Corneliani inside-the-pocket tags, so I assume the one of mine with tags like you showed is just an older model, still made by Corneliani, but I honestly don't know. This particular jacket of mine has a lower gorge and wider lapels than my other PRL jackets with more recent Corneliani tags, but otherwise similar (soft shoulder, 3r2).
