The invention relates to a western-style suit fabric excellent in memorability, good in thermal protection and easy to arrange. The fabric comprises an inner layer (1), a basic layer (2), a breathable layer and an outer layer (4). A liner fabric layer is arranged on the back face of the inner layer. The liner fabric layer comprises two parallel mesh surface layers and an elastic material layer arranged between the two mesh surface layers, wherein a plurality of through holes are distributed in each mesh surface layer, the elastic material layer is composed of any one or more of a plurality of sets of vertical dispersed linear silk elastic materials, a plurality of sets of vertical elastic X-type crossed structures and a plurality of sets of vertical U-shaped elastic rings, wherein each annular elastic ring is formed by curling silk elastic materials. The fabric is mild in hand feeling and capable of keeping external drooping feeling, the fabric is warm and easy to arrange, and the excellent memorability is achieved.
