You can start with a "U" shape from the armpits almost to the center of the chest.

Next continue the chest curves up till they point to the tops of the collars. Then copy the collar shape and make the collar longer by adding a little rectangle at the bottom of the collar.

Now draw "C" shapes and backward shapes on both sides of the collar rectangle.

Now draw smaller C shapes inside the first ones and connect them.

Then draw lines curving down between the "C" shapes.
