If the clothes have the morphs you are using on Aiko, dial them on similar settings. If the clothing does not have the morphs you use you will need other helpers - either you fix it with Posers Morph Brush or you use magnet., of course you coult use a Tool like the Tailor or Wardrobe Wizard to transfer the morphs to the clothing, too.
