wear a size 14 and the XL was too small.  The seam at the center front was pulling the stitches.  FYI - these are the EXACT same pants as the Amazon products Diamondkit Women Faux Leather Leggings Wet Look Metallic Waist Legging Pants Trousers AND the Lynley Women's Liquid Wet Look Shiny Metallic Stretch Leggings, however both of those cost a dollar less than the Nihoe.  Have included photos of Diamondkit & Lynley, as well as stretched seam.
