I stumbled upon these "crystal" chiavari chairs in a wedding magazine last week (don't judge), and thought they were pretty stunning. I love chiavari chairs, but I had never seen this rendition before. I still think actual "ghost chairs" might beat them, but they're beautiful.
A "crystal" chiavari chair.
A "ghost" chair.
...and proof why ghost chairs are incredible...
