What's the hairstyle name of this kind of bangs?

Kind of looks like a variation of the flapper bob style, just with longer sides and back.

I would say those are just regular bangs, with the ends angled to better blend with the sides (which are also angled).

I don’t know – angled bangs would seem to describe them.

They look like blunt,angled bangs to me.

http://beauty.about.com/od/hairbasics/ht/trimbangs.htm I found this for shaggy bangs and looking at the photos under shaggy bangs it looks like it might be what you are after. Long shaggy bangs is what I googled http://beauty.about.com/od/hairstylephotogalleries/ss/photosbangs_10.htm also this pic looked rather like what you want. the only difference I think is how much thickness and body she has in her hair as opposed to the photo you have up. that lady has very straight fine hair I would imagine.

They are called “Blunt Bangs”
In my opinion, although they seem to be all the rage, women with beautiful foreheads should NEVER go with this style.

blunt bangs. i cut mine myself and its really easy. although, warning: if you’re anything like me, you’ll be sick of the hair in your face after day 2. but when done right they can look really good. it just gets so annoying.

@davidk What constitutes a beautiful forehead?
