There should be files in the MAT poses folder for that costume to turn these bodyhandles on and off. Look in Poses / Spywear MAT files (if you haven't reorganised or renamed the folders. Quoting from the included readme: "WHAT ARE BODYHANDLES? Bodyhandles are bodyparts not intended to be rendered that allow advance posing of the figure where traditional bodyparts are not appropriate. They allow movement without morphs. They have their own material and should be made invisible prior to rendering."
