It's very important that you should make sure and verify your size before placing an order. All our shirts and hoddies follow these specifications. Please have a look at the help guide:
Place the end of the tape beside the collar at the top of the tee or of the hoodie (Highest Point Shoulder). Pull the tape measure to the bottom of the shirt.
Measure the front of your chest from one side of the armpit to the other. Keep the tape measure horizontal.
Place the end of the tape at the center back of the collar, then pull the tape measure along the top seam of the sleeve. When you get to the shoulder hold the tape in place at the shoulder and continue to pull down the sleeve until you reach the hem of the sleeve.
