I, too, don't have that exact skort, but got one that has a mesh short liner, too. While I could NEVER wear that thing alone, it's really not bad under the skirt (well, it's attached, so I don't really have a choice).
If it's a mesh short you should be just fine- so long as the skirt isn't really loose and flowy- in which case it could be a very "revealing" mistake.
