This PrettyGuide dress is ok, but not as nice as the PattyBoutik turtleneck dress, which costs more ($31.99-39.99).  The ribbing is thinner and the material is more shiny.  Both PrettyGuide and PattyBoutik labels (inside the dresses) say 70% viscose/30%.  However, Amazon webpage says PrettyGuide dress is 100% viscose, which may be why the PrettyGuide dress is more shiny.

Upon close examination, I think I know why this dress is advertised as "Slim Fit".  If you have very large breasts and/or hips, then you may split this dress open.
