Bust: Not your bra size! Take the tape around your back and bring it across your nipple line (typically the fullest part of the breast). Your arms should be relaxed, down at your sides.
Waist: This is the smallest part of your waist. Typically it's an inch or so above your belly button.
Hip: around hips at fullest point, taking note of how far down from the waist that you are measuring. 
Shoulder to Shoulder: Only needed for dress with sleeves. This is the width of your shoulder.
Nipple to Nipple: This is the distance between your two nipples. 
Shoulder To Nipple: Start the tape at your shoulder and measure down to your nipple. 
Shoulder To Waist: Start the tape at your shoulder and measure down to your waist line, Let the tape across your bust. 
Arm girth: This measurement gives me the size of the sleeve hole that you are comfortable wearing. This measurement is entirely subjective and you can make it as deep or as tight as you are comfortable with.
Bicep girth: around arm at fullest part of upper arm
Waist to Hem (Net Size): Measure from your Natural Waist to where you want the hem to be. This is a NET SIZE (No shoes). 
Full length (Net Size: from Shoulder to feet): This is the length from your shoulder to your feet (No shoes). You should stand upright and your feet should keep together. Let the tape across your bust (culmination) in the front and drop naturally.

Last important: Please tell me how tall your are without shoes.
