Im 5'3, 110 pounds. I bought an X small and it is perfect. I still have room to stretch. Love the pockets. It does get wrinkle out of the dryer so I pull it out of the dryer immediately and hang it.<br /><br />Deducted one star bc the fabric material will worn out eventually. I already see some signs after a few washes
