Opting for a poorly sized hoodie could make it look bizarre on your body, it’s as simple as that. So what you need to do while measuring is to use a cloth tape measure for seeking most accurate reading. Make it certain that when you are circling, the level of your circles, waist or hips with direction to tape is neither too twisted nor too tight or loose. There is no need to take the measurement over your clothes as the bare skin tends to offer a comprehensive measurement.
Simply place the measuring tape at the middle of jumper and start measuring it from back side of collar seam to all the way down to desired hemline.
Do measure entire of circumference of your chest by placing one end of the tape and sizing fullest part of the waist. In this way, tape should be adjacent to your armpits and you should be sitting on your shoulder blades for a good measurement.
