The Weihnachtsmarkt on Dorena's World (https://opensimworld.com/hop/85273) not only offers all kinds of classic Christmas decorations, but also clothes by Klarabella Karamell. Check the wooden building right next to the landing point, and you'll find some Damien Fate mesh clothes with textures made by her. They even come with alpha masks.

Oh, and don't forget to pick up the boots and woollen hats from the booth opposite.
