How to measure
Measure over a thin layer, keep the tape snug but not tight, and round up when you are between numbers.
Measure around the fullest part of the chest, under the arms, keeping the tape level.
Measure straight across the back, from the tip of one shoulder to the other.
Stand them against a wall, heels down, and measure from the floor to the top of the head.
When you are between two sizes, weight and height are the best tie-breakers for fit.
