I saw the new Purple Label at Saks. Aside from some new tags and unfinished sleeves I don't see a difference from the old Black Label. Even the fabric used on some models are exactly the same you'll find at Harry Rosen.
Speaking of Saks it's quite underwhelming but that's expected with only half a floor of menswear. The Corthay shoes are nice but very steep at $3k a pair.
