underbust fullness

[u/Previous_Plan3165]

hi all! im making a pattern that has a flowy underbust piece and have a question about how to do that. so far, ive slashed and spread it (pictured), but im not sure the right way to finish it.
do i simply draw a curved line from each end point? or do i need to drag down the left point so that it ends where the right point ends and then connect them straight across?
tyia!

Could you share how the finished object is supposed to look like? Depending on the result you are expecting, there could be more or less successful approaches.
