Measure around your neck at the point where a shirt collar band
encircles the neck.
Chest

shoulder blades.
Waist
Tape measure should be straight around the waist where pant
waistband normally sits.
Sleeve
With elbow bent, measure from the middle of your back directly below

flat across a table and measure from the crotch seam to the bottom of slacks
along the seam.
