Hi having hair cut has many styles : Long medium and short it depends on what people prefer as we are not the same taste so a new hair cut will make us change our look some are look lovely or serious so to have our hair cut it's important specially is for our style,it would make us look in different way, as you told " short hair cuts make you look shorter " ? But I don't think so, maybe it's your idea.
It depends upon your look. Normally in short hair a person looks young. But in my suggestion you need to have shoulder length hair.
Well it depends on how your face is structured then you will know
Redwine, you are absolutely mistaken and misguided by this misconception of yours that short hair makes a person look and appear shorter. Instead, to be in touch with the reality as well as the trendy world, short hair these days are really in. Apart from that, short hair make a person way sexier, attractive, smart and dazzling to everyone! So be happy with your short hair. People would be admiring you twenty four-seven!
