Hi - would appreciate your thoughts on [[http://www.johnlewis.com/phase-eight-leaf-print-dress-black-ivory/p2361219?sku=235082708&kpid=235082708&s_kenid=5522adef-0e33-4f5d-96e1-558e8d982a01&s_kwcid=403x2338758&tmad=c&tmcampid=73 this]] dress. I will be wearing it with a black jacket for my father's funeral, but am also thinking of a long-line black cardi - would that be too casual? Thank-you!
