I didn't see a length listed either, but I'm looking at the length on the model. I'm 5'9.5" in bare feet, so I figured it would probably fall to about the same length on me as on the model. I wish I had time this weekend to look for it at my local Macy's.
I have not been able to get into the idea of leggings under a dress. I rant and rave about the idea of anyone telling me I shouldn't wear something because it's not age appropriate, but that doesn't mean that I don't personally have notions for myself (not for other people, mind!) of what is or isn't age-appropriate for *me*. All of that, for this: I somehow feel like I would look silly wearing leggings under a skirt or dress.
That doesn't mean I won't try it. I try to be very open-minded about trying new things, but I'm not ready to buy a dress that would probably require wearing leggings for anything other than evening out. (I have tons of "going out" clothes already)
