I usually wear a size 7 in jeans so when I read the reviews saying the pants run a little small, I ordered them in an 8 regular.  I could have easily gotten them in a 7 as I have about three inches of room in the waist.  Im going to keep them though, as my belt and equipment will take up a little of the extra space.  I love the fabric, its not extremely heavy and that is a big thing when I live in the desert and the summers are well into the 100\s.  Reviews also stated that some were finding the legs to be tight, I found the legs to be very roomy.  The length is good for me, if anything maybe just a half inch longer than I usually wear, at 5' 6" I am usually in between that regular and "short" size, but these cover the tops of my boots without hitting the floor in the back. All in all I found these to be great pants for my work.  Its great to have something that actually fits a womans body.  Finally I can look like a female when I go to work.  Great product, well worth the cost, shipping was fast,
