It seems to just be a bob. It ends at her chin, and she just styles it curly. I dont know if there is more to it than that. and a picture does help but it also doesnt because your hair type isnt her hair type so it isnt going to be the same.
An ombre itself is easy to get done in a salon, but that exact color is not. Since it is really her pastel pink faded and then an ash blonde on top? You can see the traces of her pink but it also isnt just her pink from the other videos...so idk if you can really find a good way to recreate it without doing exactly what she did, which is not something you can explain to a salon. I also wonder if you want that exact stuff or it translated toy oru hair, since she was dying it black because her hair naturally is black, so as it grows out it is easy to maintain. If you go black on the top, you do need to redo your roots.
As for if it suits you, probably. You have a long face and so I feel like when you have hair around your face more, it helps frame it, which as of now you lack. I would also reccomend getting short layers/ bangs as well, maybe side swpt. I cant help you with cost, that depends on the salon and the person, but do not cheapen out. You want to go to a real salon not one of those fast cheap stuff becaue the quality matters.
