Farr West Response: Unfortunately, microfiber slips do have a tendency to ride up if the fit is not perfect. We believe that the fabric that we use makes the best possible slips of this type and we make every effort in our production to create a wearable, functional slip. However, fit is critical with underpinnings and it is important that it is neither too big nor too small. If the slip still does not fit perfectly, we suggest trying a full slip such as the Farr West Stretch Sensation 14" Chemise 27414. Megan from Florida
