Maybe go to a store and try them on? Or order the one that fits according to the size chart? If ordering online, just make sure they have a good return policy and take a look at the size chart. I had no problem when I had to exchange a jacket I ordered online for a smaller size - it was a great deal and worked out in the end, even though it took some time. No one can really tell you which size or brand of pants is going to fit you best without knowing anything about you, your sizing, etc.
