Yes, I have seen plus size clothing in both men and women's sizes. However, I think every Marshalls has a limited amount of clothing in these sizes. I have always found that when you see something at Marshalls to buy it immediately because you might never see it again and they very rarely check to see if other stores carry clothing that you need.
I have seen double-x and 3x, but they do sell fast because these sizes are in demand.
