I love this name. I picture a strong, artistic, elegant woman when I hear it. I much prefer Gabrielle over the trendier Gabriella/Gabriela. Sticking that -a on there ODs the name on frill and saps it of most of its class, imo.
I'm the only person I know who thinks Gaby is a cute nn. What I can't stand is Bree or Brielle, and I'd worry that my Gabrielle would get that a lot these days.
