I had this conundrum in December 2019.
I bought a Fat Face black dress from hospice charity shop for £3.50.
I bought black court shoes with gold heels from Primark for £12.
Total: £15.50
Leftover: £84.50
Use your leftover amount on an item that will bring you joy throughout the winter. I'd go with heated blanket you can use whilst reading/watching TV on the sofa.
