I usually wear new clothes for Christmas and new years.
This year I've got a dark red wool jumper
Green long sleeved top for insulation

Faded grey skinny jeans with stripes across the knees (love them, can't wait to wear them)
Some comfy boots(I won't really be wearing shoes most of the time though)
I got some hogwarts pyjamas and spotty slippers for Christmas eve too.
