what type neck line for length of hair

I don't like to see necklines so low it looks like the woman's about to pop out of them-- it's just exploitation, I think :-P . But moderately low necklines look all right.
I've been told the thing about lower necklines working best with short hair, but I couldn't follow it even if I wanted, because I have a really embarrassing scar at the front base of my neck. It's scoop-shaped, red, and has been compared to a hickey, so I'm very embarrassed of it. Even covering it up with make-up doesn't help, because it still is visibly indented. So until I can find money and opportunity to have something done to fix it surgically or whatever, I'm stuck wearing everything with a high neckline.

Generally, I feel that lower necklines look better no matter what, as they are flattering for most body types. That said, turtlenecks do look good with longer hair, while boatnecks can look nice with shorter hair or updos. And I just do not like crewnecks. Period. But that's just my own silly little pet peeve. I find that camisoles and strapless tops are very flattering on certain body types, regardless of hairstyle. Okay, taking the rest of my senseless rambling to Passion for Fashion, I think.
