I have several pair of the D&C with seam detail. They are thicker than a Tshirt, smooth knit, don't stretch out, mine haven't faded (I wouldn't want a pant out of a thinner material) and they fit great and are comfortable.
I never wear mine that I don't get compliments. They do not wrinkle and just look great on!
I will add......I have 3 different French Terry's. Quacker and 2 D&C. I have 3 different fabrics, all French terry. My grey ones look like flannel, the navy are dressy knit and the Quacker ones are not as fine a knit. The D&C with seam detail are my favorite! They look so nice on and do not wrinkle or fade!
They are nothing like "terry," the outside is smooth like a fine Tshirt and the inside is a very short loop and smooth. You have to look close to tell it is not just smooth knit!
