I've lived in Florida my whole life, and one thing Floridians can all agree on is that socks with sandals are a no-no. I can't tell you how many times I've secretly made fun of German tourists for pulling their socks up to their knees, and then throwing sandals over them. It's just not cute.
But apparently, the world of fashion disagrees, because there was not one, not two, but THREE sock-with-sandal sightings on catwalks in PARIS this week!
Yeah, I guess socks with sandals are "in" now. Or something.
I think it looks hideous, but I'm sure your grandpa will be happy to know he's been onto something for all these years. *ugh*
