They are definitely smaller and the fabric isn't much worse if you are not sure buy a size up as the elasticated cuffs will hold it up. space doesn't matter. The fabric is very thin and breathable, but definitely suitable for layering. I noticed the seams were unraveling after only wearing it 4 times under polyester pants which was a bit disappointing. If the stitching was as good as the fabric it would certainly deserve five stars.
