From the pattern description: This halter is so quick to knit, you can make it in the morning to wear to a lunchtime barbecue. You can also adjust the straps to increase (or decrease) the placement of the center V. Being a more modest type, I prefer it at midbust, but if you’re a little more daring, let it dip. The ribbing will adjust to fit your torso and bust. This pattern fits an extra-small woman (30-inch chest). Directions to fist sizes 32, 34, 36, 38, and 40 are in parentheses.
