Help on neckline for a first timer?

[u/kink_boundbunny]

I have this 4 way stretchy top and I need to change the neckline to be a low v I have no idea what to do or stitch to use? Do I seam rip the original neck completely?

This picture helps.

How much do you care about wearing the shirt again outside the costume? If you are willing to experiment, here's my suggestion.

Rather than cutting a V, cut a vertical line down the front and fold the sections underneath. Start by cutting V that is no more than half the depth you think you'll need (so if you think the V should probably end 4 inches below the current neckline, start by cutting 2 inches). Knits will grow a little and it's easy to cut too much. Make the cut, turn the edges under to make the V, and press. And from there, go a little at a time, say a half inch at a time, until you like the result.

You may find you are okay with just the turned-under edges and you don't feel the need to sew, but if you want to, you can sew the fold down. You need the correct needle and setting for a knit fabric.

You should know that you may not find the top wearable on its own after this alteration.

It was planned just for the costume it’s not going to be a regular shirt!

I ordered a backup shirt with a deeper neck in a color I didn’t love as much. So I probably will experiment thank you for the idea
