Necklaces, belts, and bracelets should add some interest and texture.
I am taking several blazers, some solid (tomato red, black) and some textured/patterned (leopard print, cream and grey tweed). The top piece is a fur vest which can be layered and goes with almost everything.
Ballets in a nude and perfect suede will give my feet a break from boots.
One clutch for night and two scarves round out the add-ons.
