T-shirt with chest pocket in polygon design

That's how you measure correctly

The information in the table is dimensions of the garment, not your body measurements. It is best to put a well-fitting T-shirt flat on the table and measure by this example:

• Breast width Place the top flat and measure from armpit to armpit. The breast width results from this distance (if required x 2 for the circumference)
• Waist width Measure at waist height (slightly below the chest) from left to right, while the Top is smooth on the table.
• Hip width At the bottom end of the top, measure from left to right.
• Sleeve length Measure from the shoulder's base (shoulder seam) to the end of the sleeve.
• Back length / length of the item The measure from collar base (rear, center) to hem below is the length of the T-shirt.
