J.Crew is adding a new option to its Ludlow line and it'll be their most affordable option to date. Their new "Un-Suit" style is unlined and unpadded and is made from English wool-cotton twill from Abraham Moon. The fabric is an ideal weight for transitional weather and is a solid option for fall. The suit will come in their slim-fit cut and is also available in stretch cotton and cotton-linen.
