I just got my hair cut into a bob that's very similar to Mayim's pictures on Friday. It's about chin length in front (plus bangs on one side), and shorter in the back. I wasn't so sure about it for the first day, because my stylist had used volumizing mousse in it and it was huge, but now that I've had a chance to style it myself, I LOVE it! It's very easy to style and it dries sooo fast.
I've been gradually going shorter since about April. My hair was BSL a year ago, then I cut it to shoulder length and had it tha way from April until Friday. I don't know if I could've done BSL to chin-length without a major anxiety attack... but I sure do like it.
