The doctors have measured me anywhere between 5'8.25" - 5'9.75" But I have never reached the 5'10" in their office. It 's so funny because people get the impression that I am easily over six feet tall ( I have excellent posture, and I never slouch). I think they are overwhelmed by my long limbs... I wear a 36" inseam pant!
My usually answer... "Oh, about 5'10" LOL. If I said anything less, they would think I'm delusional.
Tall, short and average girls out there, be PROUD of your height. I even like to emphasize myself with tall heels! Do what makes you feel and look good!
