This style looks great on you! I'm glad you're trying out different things! You'll never know if they work for you until you try them out. Isn't it fun experimenting with hairstyles... well, when you're not busy doing other things :-}
Very neat twists, I like the even size! I'm still surprised that you can't bun yet. Have you tried doing them on stretched hair (braidouts, twistouts)?
I love this!!! Very thick and beautiful hair. If you see the classmate again, you can always inquire about the style and let her know that you're interested in replicating it. I also think that Perdepthtion does a variation of this style so you could check out her fotki and ask her.
Great shot, beautiful texture! Your hair has really grown a lot since spring, it looks like it's past your ears now. It was probably past your ears before, but you know how shrinkage is lol! What has been your regimen?
