The Pleated Fog Trouser is supposed to be an even wider, more relaxed version of the regular Fog. In this case, it’s done in a vintage French moleskin from the mid-60s. It sports one sterling silver top button and two side seam pockets with slanted back darts. The pleats give a substantial amount of room in the thigh and down the leg.
The pant is patterned to fit a medium / 32 - it's recommended to take true to size or size up for a more relaxed fit.
