FAB or FAD: Garter Style Leggings

I was doing some online shopping today when I sashayed over to GoJane for some last minute vacation pieces. In an attempt to find a pair of riding pants for a horseback riding session I plan to have, I couldn't help but notice what seems to be a new trend coming to surface. Garter style leggings...
I wasn't sure what to think, but of course, I ordered some! And as of right now, I think I love them...

What do you think?
