I am not particularly keen on 'alternative black tie', nor am I very enamoured by the idea of wearing faced-lapels with conventional dress. However, when heading out for dinner recently I considered all the options for a sober lower half (slim grey trousers, black loafers) and decided to go with the shawl collared dinner jacket.
It's not 'correct.' It might even offend some, but this was exactly what I liked about the design. It looks cosy and elegant and it is rather like a smoking jacket in terms of versatility.
