Where is the "Click Here" info for SG items?

Having more and more difficulty with finding the correct size with SG's clothes so always need to look at the "Check Here" section for details...sometimes according to that chart I can range between an XS and Med.! No kidding. Today wanted to buy her Stretch Velvet Slim Skirt and guess what...no "Click Here" and the graphic on screen was showing chest measurements...for a skirt. What gives? Too expensive to guess and have to return so skipped buying. Frustrating.
