I keep mine curly because I can't wait to see it get longer!!! I'm starting to think that the more you wear it curly, the better your hair will look over all. And I've grown to LOVE my curls! I'm 3c ish, I have some looser sections and tighter ones, but the tightest curls fit around a pen, soo I would say 3b-3c, and an very tight 3c. 3's are complex :/
