Classic dark navy blue Pierre Carin poorboy rib knit top with white embroidered logo on the left chest, circa late 1960s to early 1970s vintage. Scoop neck with ribbed trim. Very slim fit - long and lean. Short sleeves are designed to be cuffed up, but can be worn uncured (reverse seam at last bit of sleeve length). Straight / unbanned hem. Content and size aren't noted- this looks and feels like cotton or  a mostly cotton blend. A fair amount of give allows for a range of sizing. Fine gauge, lightweight.

Condition is very good or better- spotlessly clean. An old repair to a run on the underside of the left sleeve- not visible when worn but noted for accuracy- does not detract. No thinness or worn spots- the white of the mannequin is simply being augmented by the camera's flash. 

An exceptional piece!
