I buy many pants by this company and these are a full size smaller than their already sized down clothing.  My pants are size 10 and the large was way too small for me.  It was like trying to pull a size 6 or a small running size 8 on.  Seriously, I couldn't get into them.  This company is not good at quality control when it comes to sizing.  I have some mediums that are loose on me and other larges that are snug, but these were  ridiculous.  I wish they had an extra large, I would have bought them.  I thought they looked great and had similar craftsmanship to the several other pair of pants I own by Kuyuansu.  That craftsmanship, however, does include belt loops that will pull loose if one uses them to pull up the pants to assertively.  Also, the waist buttons have come off.  I just use my belt and fix it when I get home.
