Welcome I am aweful at typing hair..you may want to post this in general discussion and let the other curlies give their opinion. Its kind of tough by looking at the pic cuz it is not close up. Post it in the other forum and Im sure you'll get lots of advice on styling and taking care of your curls
Hmm, it's kind of hard to tell because of the lighting (although I did click o the picture so I could see a bigger version), and because your front half is pulled back, but it looks like you could be anywhere from 2c -3b. Would love to see a pic with all of your hair down! Welcome to the forums!
