I have been searching for a full length slip that does not show through my clothes.  The ones with lace and darts or tucks show through and I want a smooth front.  The top fits great and is comfortable.  However, as I have some weight around the middle, it fits very snug even though I ordered a size larger than I normally would.  It is a real guessing game to find a good fit and smooth especially as I have a problem finding the full slip in stores in able to try it on.
