Dimity is a sheer lightweight cotton fabric. It has a plain weave with a raised warp that forms either stripes or checks.
It is usually white on white but does come in colours and can incorporate complex patterns using the double warp thread.
It drapes well and was popular in the 19th century in women's apparel.Because of the double warp it wears well and was more for day to day wear than Sunday best.
More often appears these days in upolstery, curtains, and other soft furnishings.
