Not sure why the strong hate. I have two of these unlined Regent jackets. The cashmere and a blue check. They can easily be taken in at the waist and do well in temperate climates without adding a ton of heat from a lining. I have strong shoulders and this jacket conforms to me.
The charcoal doesn't look like an orphan in person. The texture is a bit rougher than any wool suiting. I wear both jackets with light pants and love them.
