See fabric information for color information. The linen I get is usually a seasonal run from the fashion industry. It is left-over after the original clothing run is completed or it was a bolt sent to a design house to make up a sample piece. When I get it, there is no information on the oz. One fabric is called one name for 50 to 100 years and then when the call for it decreases, they slap another fashionable name on it and hype it some more.
Industry can call any weight by any name it pleases.
Call it an approximation. And linen is made in different ways. The shorter fiber linen feels softer from the start. It breaks and loosens the fibers and the ends stick up more. I machine wash my linen garb, then take it out and shake it, hang it up and hand stretch it to smooth most of the wrinkles out.
