Order at least one size up.... maybe 2
I purchased a pair of pajamas and I ordered them in XL because I like pajamas to be loose. When I opened the package I was excited that the colors were just as gorgeous as advertised. I was disappointed that the fabric was not as soft as expected but the real problem was the sizing; they are cut quite small. Based upon the XL I ordered, I would need a 2 or 3 XL in this product (I wear size US 14 pants and those are typically a bit loose).
