Some people say that braids are childish, but on the other side there are many women who braid their hair, especially since it became a trend. I think that side braids styles look good on me but I'm still reluctant to wear them outside the house
I voted D. Some girls just look gorgeous with braids :D On some girls they're not beautiful at all, but it doesn't relate too much to age. And if I'd have to name an age than make it 40 :D I'd be happy to give feedback on your braid (s) and I'm fairly certain it will look nice!
It really depends on how you do it not on what you do... As with anything the style of what you wear should be suited to your age... Leather pants with a blazer - nice for a 35 year old. Leather pants with a tank top - a bit much for that age... Same premise, different style.
I'm 19 and wear pigtails in plaits at work all the time. I was worried it'd look childish but it holds my hair in place way better than a ponytail and besides, if anyone says it's childish just refer to them as handlebars ;P
(Don't really do that haha. If you're happy wearing them go for it!)
