These are a tad tight around the waist & buttocks. I knew Dickies ran small but this was still a shock considering I am only a size 12/13, the pair I purchased is a 14 which I thought would give me the roominess I desired. I like that in a frigid place like New England, these were good for me on a night of 42 degrees with a hefty wind chill. On colder nights I wished I was able to wear a pair of leggings underneath them. The jury is still out on whether I would purchase them again...
