These shorts fit probably as they should. I typically wear and 8/10 due to my waistline.  I ordered a large, but should have ordered a medium.  I just wasn't sure how tight the waistband was going to be because I do not like tight waistbands which are not only uncomfortable but create the muffin top look if you have extra weight in the waist.  These shorts are comfortable but do have a heavier weight to the fabric than I was expecting.  I'm keeping my large but will probably order the medium if I get another pair.  They are comfortable, but I had wanted something with a little thinner materials especially as the pockets add more bulk.
I gave the four stars instead of five because as at least one other reviewer mentioned, the material can gather in between the legs when you walk.  Since I ordered a larger size, I am a little concerned the gathering will only be worse with the medium.  My weight is mostly in my stomach (apple shaped) so my thighs are not real bulky.  So for the fabric to gather in between the thighs, I can only guess it is due to the thicker fabric.
