This bed skirt is described as having a 16" drop, but it actually has an 18" drop so it was way too big on the bed.  I didn't feel like returning it and searching for a new one, so I pinned it on one side to get it to the length I needed.  The mattress seems to be holding it in place fine and so far its ok.  I do like the look of the bed skirt, it has a very casual vibe and you can't see through it which is good for me since I store a lot of stuff under the bed.
