Black Convertible Crew

Size Guide
Selecting the Right Size

Your measurements will be most accurate if someone else measures you. Make sure your feet are directly under your shoulders, and let your arms hang down by your sides (see photo for reference). 


Measure the circumference of your chest at the fullest part. Under your armpits, around your shoulder blades, and around the front of your chest.

Measure the circumference of your waist at your natural waistline. If you bend to the side, the crease that forms is your natural waistline.

Measure the circumference of your hips over your hip bones and around the fullest part of your buttocks. Please do not use your "pant size." The actual measurement will be more accurate. 

Use the chart below to determine your size. If you're on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If you're measurements for chest and waist correspond to two different suggested sizes, order the size indicated by your chest measurement.

S 36" - 38" 29" - 31" 36" - 38"
