This slip comes down to mid-calf on me (however I am 5'4" tall).  So I can't use it for the dress for which I bought it, which is knee-length.  Unfortunately, there is no way to cut the bottom to adjust, as there is on some slips.  When you are buying online, keep in mind that "half slip" means anything from a garment that barely covers your rump to one that would be worn for a cocktail-length dress.
