It’s worked top down making the first 2 rounds for the shoulder straps and then we will work the front and back side separately for a few rounds to shape the arm holes and to make the top of the dress. After these few rows we will join the back and front and start working in rounds again.

To create this V shape in front we will increase in middle of the front and back. After joining the parts we will have to decrease on sides to keep the dress straight.

We will work in this V shape a few rounds and then we will fill the sides to make the bottom straight. After we have the bottom straight we will continue working on the length of the dress as many rounds as you want until you get to the desired length.

On the back I designed a deep neckline, but if you want you can repeat for the back the same pattern as for the front and in this way you can have a shorter neckline. I will give you more details in the pattern how you can do that.
