How to knit cups for a top or bikini swimsuit

"We knit half double crochets with a yarn over into the back loop. If the yarn is thick, you can use regular double crochets without a yarn over.
1st measurement (it’s better to hold the knitting directly against the chest, not relying on a centimeter).
A chain from the nipple to the desired depth of the bodice towards the armpit. We knit a rectangle with turning rows from the line under the breast to the nipple, i.e., from bottom to top.
2. then, while knitting the next row, we do not stop but "turn the corner," knitting 3-5-7 stitches into the very corner of our rectangle in the turn. See number 3 in the drawing.
3. returning back in the next row, again knit 3-5-7 stitches into the same corner. The number of stitches depends on the depth of the bust. See number 4 in the drawing.
4. then we knit as usual, counting our fans as regular stitches.

IMPORTANT!!!
1. constantly check the number of stitches in each row to avoid losing track.
2. while knitting the second cup, you will have to cut the yarn and, carefully laying cup #1 and the rectangle from cup #2 opposite each other, adjust the direction of knitting to achieve symmetry.
