A step by step tutorial on how to crochet the Wavy Bralette.
Note: US abbr pattern

Get your stitch markers ready!! (You can also use bobby pins or safety pins.)
Think of a straight line going down the middle of your body: from the tip of your nose down to your belly button. This line will separate left side of the bralette from the right side. When you are crocheting the bralette, you’re going to mirror what you did on one side and apply the same process to the other side. For example, when the pattern says “sc until you reach Measurement X, sc2tog, then sc until you reach the middle and mirror the same process on the other side,” measure Measurement X from the opposite end, place a stitch marker 2 sts after the measurement (because you’re going to crochet them together). Then sc until you reach the stitch marker, do your decrease, and sc until the end of the row.
