Attach the yarn to your crochet hook using a slip knot, then work a foundation of seven chain stitches. Single crochet once into the second chain from the hook, then work one single crochet into each remaining chain of your foundation. At the end of the row, chain one. Turn the work over. For the second row, work one single crochet into each single crochet of the previous row. At the end of the row, chain one and turn the work. Continue to work rows of single crochet until you reach a length that matches your measured waist size.  You should use a measuring tape to check the length of your waistband, but as a general guideline, make 140 rows for a small, 148 rows for a medium, 156 rows for a large, or 164 rows for an extra-large. Note that you will need to make button holes on every sixth and eighth row. See the next step for more details. Create a button hole on every sixth and eighth row across the waistband.  To work a button hole:  Single crochet once into the first two stitches. Chain two. Skip two stitches. Single crochet once into each of the last two stitches. Chain one and turn as usual.   For each row following a button hole row, work one single crochet into each single crochet and two single crochet into the chain-two space. After your final row of single crochet, match the first and last edges, then slip stitch each pair of stitches together.  The stitches of both ends must line up evenly when you slip stitch them together. Completing this step should form a loop. Turn the band so that the slip stitch faces the inside. From now on, keep in mind that the slip stitch should face the “wrong” side of the skirt. Turn the work so that the long edge faces you. Chain one, then single crochet once into each stitch along the side.  The total number of single crochet in this step should match the total number of rows previously worked for the length of the waistband. After you complete this step, the waistband is complete. Do not fasten off the yarn, however.
