LE Minor Armour Change Request

[Natural20]

Pretty simple request

 

I'm looking to try to remove the rear shirt tails from this armour: It should be fairly obvious, they're the white pieces of shirt that stick out below the main body of armour.

I've smashed my head against a wall with attempting to use blender and given that the change is so small, I figured it might be better just to ask someone wiser than myself, rather than try to learn the entire thing so I can cut two pieces of cloth off a shirt.

 

Thanks
