How do I make a whole in the neck for a shirt?

Hey everyone, I made a shirt in roblox (had some help by someone) and the shirt currently is like- the top of the torso is flat. I wanna know how to make a whole for the neck/head.

Not quite sure what you mean… but I would recommend making a hole in between the top of the torso and the neck by erasing it.

Sorry, I found it hard to explain. But that solves my question lol, thanks! : D

Here is an image I found online, this is where the hole should be so that the neck shows.e744288cd7f1e82724d44db4412ef8a0
