Shirt became sleeveless

I’m trying to make a shirt but it’s sleeveless for some reason?

You used the wrong template. I’m not too familiar with clothing but that’s a TORSO and LEGS template. You should be using this template instead so you can make the arms.

I think you have to remember that you need to make every side of the shirt you want to make. Yours messed up because you looked at it from only one perspective. The TORSO is specifically for the torso section and does not include the arms. I’m assuming this was just a careless mistake lol.

Also, shown here is that that template does not use the arms. Only legs and the torso.
