I'm in the same boat. I am growing out a chin-length bob and it only looked good (IMO) straight. I don't want to deal with the damage of heat styling anymore, but I feel like I look like a child with it curly at this length. I'm going for a Devacut at the end of the month and I'm hoping that will help with shape b/c it doesn't have any right now.
VERY fine 2B/3A hair
Chin-length - growing it out...again.
