I would advise against a sweater for "formal dress". Sweaters are "casual wear" or in the case of a kilt, "casual day wear", a notch or two below the tweed kilt jacket. They're fine for a casual event or outdoor activities, though.

A dress shirt is appropriate with a kilt, especially with a kilt jacket. I'm not a big fan of button-down collars myself, except for very casual shirts.
