How long would 16'; hair extentions come down to?

Ive ordered some hair extentions but im not sure how long it comes down to, Some people say its just above your boobs? :S I need to know so i can know whether to get it trimmed when it arrives? And also if it is double weft, is that really thick? Help please! =]How long would 16'; hair extentions come down to?
get a piece of string and measure it out. Christ.How long would 16'; hair extentions come down to?
Depends on the size of your head, do you have a long neck.lol I`m serious!! When you have them in your hair, then trim if needed. If I were you ,get someone who knows what they are doing. You might cut too much off. Double weft is thick, but will be okay.
I have 16 inch and it like touches the middle of the boob, and I have big boobs so yeah ;)
Shoulder blades
Erm I'm guessing it would come down 16 inches


Jeez


Get a tape measure or something!
I think that's about right but it does depend on the length of your hair.
