I love headbands haha I feel like they can be so childish though and I only say childish because the one I'm wearing now it's a big pink and white polka bow haha oh well I love them :) so head bands or no headbands.
It really depends on the face and hair of the woman to be honest. It works for some and looks bad on others. Looking at your picture I think it would be okay for you to wear one but, again, it's difficult to know without actually seeing it (this is not a manipulation but a simple statement).
The way I see it, if you "love" them then who gives a shit about what anyone else thinks? Do what makes you feel fun, happy and confident and never worry about what outside sources, who mean absolutely nothing to the scheme of your life will say, think, do or whatever. Truth be told you're a beautiful woman so you will always have jealousy from certain women & a ton of leeway from men in terms of your fashion sense (unless specified such as a cocktail party - which I'm sure you already knew but just throwing it out there as I don't know your exact mentality). In other words, wear what you want.
If its fits you nicely, I find it beautiful. It's a bit like hair braids: 70% of girls would not look nice with them, but on the other 30% they make the girl look so gorgeous as if she's from heaven! By the way, since I asked some questions on these subjects I did my research and did you know you can create the effect of a hairband or diadem with a hair braid? Look at the pic below, isn't that splendid? The google search term was "diadem hair braiding". img1.etsystatic.com/.../...70xN.436601041_f4l6.jpg
Yes, something about Headbands on girls with high foreheads are sexier than hell ,, Many girls wear them i see girls my age 40's and younger age girls wearing them too i don't think age has a barrier on headbands
