This is a formal wine bag containing something clearly very valuable, given the padlock, and in it she looks like the leader of an extremely chic and super weird cult that secretly meets in posh flats all over London to plot revenge and do general witchcraft, and if she invited me to one of these meetings, I would be both terrified and intrigued and I would definitely go and just hope someone gave me something appropriately unhinged to wear.
Speaking of appropriated unhinged:
Your bedroom slippers have gotten too big for their britches!
