Men's Two Palms rayon shirts have Coconut Shell Buttons.

Note: The measurements within this size chart were obtained from actual Two Palms shirts and NOT from a body.  The Chest measurement of a shirt is realized from a measurement taken from approximately 1/4" under the armpits from side seam to side seam.  Measure the back or the front of a shirt in your wardrobe, from under the armpits, and then DOUBLE this measurement to obtain the chest size of the shirt. Compare this measurement from a shirt in your wardrobe to the size chart above to purchase the correct size. Purchase the nextt size up if in between sizes.

The Length measurements are taken from the back of the shirt from the middle top of the collar down to the bottom of the shirt hem.
Shoulder measurement is determined from the inseam of one shoulder across to the other shoulder's seam.

CARE & CLEANING: Dry clean or machine wash with a mild detergent in COLD WATER, use a delicate cycle, DO NOT use bleach. Tumble dry in cool temperature and touch up, if necessary with a cool iron.
