What will you be wearing for Xmas day. Will it be dressy or casual? Personally I like to wear a dress with some dressy earrings and flat shoes. Plus the essential apron/pinny to avoid splashes of turkey fat spoiling a nice dress.
After all that food you may well feel like a brisk walk to shake down all those calories. In which case a classic pea coat bright red sweater paired with jeans might be a good choice. A cosy beanie hat and sturdy boots are practical additions.
Later in the evening, depending on what time you eat your Xmas dinner you might fancy a change into a pair of pull on palazzo pants and a cosy cashmere sweater. The white Stan smiths can be replaced with warm house shoes or slippers.
