Agrace, have you ever checked out the naturallycurly site? I would say it's the youlookfab of the the curly-haired world
I learned so much from reading that site, I can't begin to tell you. I know there was an old post here where some of the members revealed themselves as naturally-curly's "Curly Girl Method" adherents. I follow this program, and it has dramatically improved the condition of my hair-although I haven't had a cut in about 6 months, so it's looking a little crazy lately, lol! The site also has a bunch of ideas for updos and other styles.
One thing I noticed recently, is that if I think of my hair as an accessory, it's easier to achieve a polished look. Although curly hair will never really look "buttoned-up" or "prim," I think it can still look polished. So if I wear something sleeker, I will leave my hair down and curly to add something "special," but if I have on something more voluminous or something heavily patterned, I will wear it up or straightened to make sure that it's not "too much," visually speaking. I'm not sure if that makes sense, but it seems to work as a way to balance out the overall look.
I also tend to (although it's not a strict rule) wear a necklace and/or bracelets if I have my hair curly so there's not to much going on "up there", and if it's straight, I try to wear pretty, feminine earrings to soften the look. I've been told throughout my life that I look intimidating (which totally befuddles me, since I'm pretty goofy and tend to laugh and smile a lot), but I think it has to do with my features, and it is what it is. I think wearing my hair curly or wavy mitigates that a little bit and makes me look more approachable.
I don't think there's anything wrong with playing around with your look, but I do hope you learn to love your curls! We've been inundated for so long with the ultra-flat-ironed look, but really, throughout most of history, women were in search of curls, waves, and volume, so consider yourself blessed! It does seem like we're (finally!) swinging back in the other direction, with more women embracing their natural texture. I know I feel more like "myself" when I let my hair do its thing, even if it does drive me batty on occasion!
