Measurement guide

It's best to measure with shirt.
1. Measuring Your Height
Standing, place a flat ruler from the bottom of your shirt collar in center back. Measure from that point down to the floor. It's best to do this shoeless.
2. Measuring your shoulder
Place ruler from the point that connect with sleeve of right shoulder to the same part of left shoulder.
3. Measuring Your Sleeve
Measuring from the top of sleeve to your wrist bone above the shirt’s cuff 2cm
4. Around biceps
Measuring the biggest part of bicep
5. Armhole
Measuring around the armhole
6. Measuring Your Chest
Place a tape measure around the widest part of your chest, starting from your armpit completely around your torso. On average, there will be a 15cm difference between chest size and waist size.
7. Measuring Your Waist
Your waist measurements generally should not be any different than your normal waist size when purchasing a pair of pants. For an accurate measurement, wrap a tape measure around your midsection all the way around.
8. Measuring Your Hips/Seat (OPTIONAL)
Wrap a tape measure around the fullest part of your seat.
