Pleather Skort: Zara
Boots: Pull&bear (similar here)
I'm the least Christmassy person ever so, if you're looking for someone who gets all dressed up for Christmas dinner or for family reunions, that wouldn't be me.
Since I'm very casual, this is what I would wear for this special festive day. The hat might be a little bit too much but you can just take it off if you want. Since I'm wearing a very neutral and minimal look, I added some color on my lips to make it stand out a little bit more rather than being just a plain look. If you want to look more dressy, you can swap the boots with a pair of heels.
What's your Christmas dinner outfit?
