I bought this at a time when I was super busy and didn't have time to go to the store to find a new pair of pants.  I have these in the dark blue color and LOVE them!  I ordered the same pants in dark blue, this tan/khaki color, and black.  All the same size.  The dark blue fit perfectly!  The black ones were a great length but I couldn't even zip them up they were so small!  The khaki one's were about 6 inches too long and I could almost zip them up but not button them.  Again, they are all the exact same size.  I even checked the labels inside the pants.  And now that I finally have time to address the issue, it appears I'm too late to return them.  I would really like to send them back and get recommendations on what size to order the various colors in.  I'm also really disappointed that the different colors are completely different sizes.  The most disappointing part is that I really love the dark blue ones, they are really comfortable.  I wanted them in different colors so that I could wear them to work.
