Old Script VS. Zapfino
I'm pretty sure I'm not the only one out there that absolutely HATES Zapfino. This font should seriously die an awful death. The spacing, ascenders and descenders are ALL messed up. Please do everything you can to avoid this font. Instead, try Old Script, England Hand, CAC Champagne or Chopin Script.
Learning Curve Pro VS. Curlz MT
Curlz MT is another font that has made it's way into way too many invitations. Girl parties, baby showers, I've even seen people set this as their standard email font. PLEASE NO. If you're looking for a girly font and want your classiness intact, try out Learning Curve Pro or Marketing script.
Blokletters VS. Comic Sans
Comic sans could probably die, too; it's over-used and old. Comic sans is an informal font, which I often see in more formal settings. NOT COOL. Stand out from the Comic sans crowd & try Blokletters or Quicksand instead.
Chantilli Antiqua VS. Papyrus
