I'm a 3a/b and have a pixie. Got it cut 5 weeks ago. Don't have great pics but maybe I can help. It was cut really short, like Charlize Theron at oscars but I don't push up the front. At that length my hair doesn't curl or wave yet. I also don't blow dry or use flat iron. I always let it air dry. It's been 5 weeks so now the top is a little longer and has some wave but I use it to make my hair messy/piecey.

I think with curly hair, the pixie will not be as wispy as Michelle Williams unless you want to blow dry and/or flat iron. You can definitely pull a Halle berry type pixie easily. Curly hair's innate texture allows for messy pixies but a sleek pixie will require work.

It is definitely do-able! Good luck.
