How can I style my hair to look like this?

Ok, so this looks really simple, like you just take your curling iron to the ends of you hair and curl, right? Well I tried and as usual I came up with something totally different. So I'm wondering what I'm doing wrong... The result of my attempt was a sort of flipped out look at the ends of my hair instead of ringlets. Could this be because I already flat-ironed my hair to get rid of the natural frizz and weird wave? Or is my curling iron the wrong size (a medium barrel)? If you have any advice please let me know!
