Ditto the approbation of the colour and especially the cable pattern. As for the patterned cuff, I would defer to the traditionalists about the wedding. However, for wearing on other occasions, I have often been gratified how bold ideas come out. If you don't mind tearing it all out, you might just go ahead and see how it looks. Then you will know rather than always wondering. Sorry if that is less than definitive. Good luck.
