Braids. You may need to practice at first, but once you get the hang of it, it's done in a few minutes. I like dutch braid (or french braid, depends if you like braiding under or over) when i want no hair in my face. You can add a ribbon for fun.
One cute feminine style is to french braid one side towards the back of your head. Grab the rest of the hair in a low ponytail, bun it and use the braided hair to wrap around and hide any elastic or pins you might have used to secure the bun.
I suggest you watch TorrinPaige on youtube, that woman has a fantastic long hair and she does tons of lovely tutorials. Another channel i love is CuteGirlsHairstyles, they're made for little girls but i think most of them look very nice on a woman as well.
If you have short hair, think about combs, they're nice and elegant and they dress up any hairstyle, imo.
Videos i suggest :
3 messy bun looks
Nautilus bun
Infinity/figure 8 bun
One last idea is a french twist, i'm not very good at it, so i just twist all my hair and use a regular hair claw clip, 30 seconds !
