I recently bought a Â navy blue wool, and cashmere three button sports jacket that is Donna Karan Signature. I will be going to an evening opera, and am wondering would it be appropriate to wear a white Mani French cuff shirt with a set of S.T. Dupont cufflinks, and an Alfred Dunhill regimental tie with very thin green, and red stripes on a navy blue background. Also would a matching round tie pin be appropriate? Your opinions would be appreciated.
