Carla, I would like to add that brocade sounds interesting to me because of its "three-dimensional" look.
I must admit that I first and foremost associate brocade with formal wear, and though a brocade waistcoat could be a fun, playful addition to my occasion wardrobe, I don't intend to buy partywear this year, as I am mainly staying at home, caring for my old parents.
However, I suppose that brocade can also be found in everyday/casual items, and perhaps your photos were meant to illustrate this, but unfortunately they are so dark on my screen that I can hardly see the brocade. Thank you for the inspo anyway.
