This is a Lucien Pellat-Finet raglan sleeve knit, believed to be an archive piece from the 2000s.

Unlike many Pellat-Finet items, this one comes in a rare solid color.
The care tag is missing, but based on the texture, it appears to be cashmere.

Size M, brand new with tags.
Manual measurements:
Chest width: 52 cm
Length: 67 cm

Please note that this is a vintage item kept in personal storage. Purchase only if you understand the nature of archive and pre-owned pieces.

Lucien Pellat-Finet gained popularity when Japanese celebrities such as Takuya Kimura and Tsuyoshi Kusanagi wore the brand’s T-shirts and knitwear. More recently, stylist Tsuyoshi Noguchi became the brand’s artistic director, bringing renewed attention. Although many counterfeit items exist on the market, this piece is guaranteed authentic.

I am also listing other archive items, mainly the following:
UNDERCOVER: Scab, T, But, Arts, Languid periods
Number (N)ine: Kurt, Dream, Give, Rose, THS eras (original Miyashita-period works)
