Should I get highlights, and what hairstyle should I get & other hair questions!?

I've been using sun-in for awhile once a week. As you can see, I have dark under-hair. I've never had my hair colored professionally before. If I were to get highlights, I would want a lighter color. If I should get highlights, how should I get them, what color, and if possible; include pictures of what the highlights would look like.

Hair down:

I will be getting a tan soon, by the way.

My hairstyle right now is subtle sidebangs with long layers. The sidebangs are blended in with my long layers. My hair is about 3 inches below, and I have no idea what my face shape is!

My questions are:

Should I get highlights, if so; what color and how should it be done?

What hairstyle should I grow/get?

What face shape do I have? (pic below....)

well as a salon owner and experienced stylist, I have to say that your hair looks very good now, and if you where to have highlights I would say very subtle caramel or blonde ones

the style only needs a tidy up, but looks very nice

I would certainly consider you to be a salon model with hair like yours, well done it suits you very well

you should get really light highlights and they should be very thin, so they look natural. your length is really good, so just get a trim. and i think your face shape is oval???? not sure. lol.
