On the JLC Boutique front I went into the Boutique in London looking for a coloured faced Reverso. It was only after trying all them and many others that I decided to buy there and then the bog standard, without second hand, GRUT. As is often said try them all on and buy the one that sings to you.
It could be worn as a dinner jacket if you found the trousers to go with it. Unfortunately only velvet jackets and the more outré coloured and patterned DJs can be worn with any old black tie trouser. So yes it is an orphan.
