Take your measurements directly on the body with a measuring tape around your bust, waist, and hips without over-tightening.
Sleeve
Find your sleeve size by measuring your arms from shoulder to wrist.
Shoulder to shoulder
Measure across the curve of your shoulders to the outside edge.
Bust
Measure underneath your armpits around your chest to find the circumference size.
Waist
Place the measuring tape below your rib cage and above your belly button at the smallest part of your waist. Make sure the tape is snug against your body but not too tight :)
Hips
Stand with your feet together to wrap the tape around your hips and the roundest part of your rear, usually 8-9” down from your waist.
