I bet they had a meeting to plan this event, and one person said, "Let's corner the market on female networking events. Let's invite all the female execs, and give out pink gift bags with pink ribbon and nail kits!" And another person said, "That's really risky. What if it backfires and we look foolish? Pink ribbon?"
It totally worked! Any time that someone would like to host a networking event involving champagne and pedicures, I am in!
