Do you need a certain face?

I am not sure there is a special type of face shape that side burns look better on vs another. I think it will be different with everybody. You would have to get them done and see for yourself. Find a couple of friends that will be honest with you, and have them give you an opinion after you get them done. Be sure to let them know that you are not taking it personal if they don't like them.

i got side bangs I wasn't sure it would look good on me either but this convinced me link you upload your picture and you can see how you look with different hair styles and hair color and it's free

Yah go for it.
If you're gonna have them pretty long, then you can always hide em later on when you don't feel like having bangs. you know what I mean? Or you can clip em or something.
You won't regret it. And if you don't like it, you can always grow em back.
Bangs would look good on anyone, depending on the cut. So have your beautician advice you on what style would look good with your face shape.

Some styles look better depending on the face shape, but pretty much anyone can pull off side bangs. I wasn't sure how they would look on me, but I got them done about a month ago and I'm happy with them. When you go to get your hair cut, talk to the stylist about it--they'll know what works best for you.
