Wearing a sweater over your wedding dress, you ask?  Baby, when it's cold outside you can mix sportswear with gala and believe me it's gonna look great!  Think about some of the poshest knits--angora, mohair--how elegant can you get?  Right up there with furs if you ask me.  Add to that sweaters are trump at keeping you snug and cozy in those sub-zero temps.
