pastel green tank top shirt

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.
