Flat chested 4-armed torso

I really wanted to create a four-armed doll using the Alice 4-armed torso but was sad that there was only the large chested one while I wanted to create a flat chested doll.

I literally learned how the hell blender works for this so if there's any issues, that's why. The scale is the same scale as the 4-armed Alice, not as big as the original Polaris, but I imagine it can be scaled just as easily
