90% of women who show their pictures here show measurements from the back, and using their nape/longest layer to define their length. If your nape hair reaches bra strap, and you define that as BSL because you like layers, then you're BSL. Personally, I don't see why people are so shocked that is only 12 inches on some women. I am about average height and bra strap is definitely 12 inches of hair from nape to ends.... Some people may be tall, or have long necks, or a long torso etc. To each his own!
