I don't know what a Hitler youth haircut looks like razz I Googled and found
I guess it's a trend? A kid in my history class has it. I personally like it. I say go for it! It's unique and stylish. I just wouldn't refer to it as that when you're getting it cut... just bring a picture and ask for it. And not a 1930's picture of a Hitler youth xD
Do. It. But then, I think that hair style can be incredibly sexy so I may be just a tad biased. I wouldn't completely shave the sides of the head like in the picture, rather have it just a tiny bit longer so it's not quite as abrupt.
