Houndstooth tweed is a check fabric, but the check pattern has notches in the corner, resembling those of a canine tooth. Houndstooth is a fabric that is mostly used for jackets and coats, and pants.
This is a fabric of choice for men’s clothing for Fall / winters.
A popular color combination in houndstooth fabric is black and white, though other combinations, such as blue and white or pink and white are not uncommon.

Houndstooth fabric resembles wool in its texture and feel, but is often woven in cotton, if not wool itself.
