Taylor Swift fans are used to seeing the stunning singer show up to red carpet events in gorgeous, priceless couture gowns or looking decidedly retro yet equally fashionable in some of her videos. She always looks beautiful. But even with an enviable closet such as hers, Swift isn't above rocking a pair of matching, flannel Christmas PJs with her baby brother Austin.

Swift shared the Christmas Day photo of herself and Austin, who is almost three years younger, cloaked in red onesies. They were clearly in the Christmas and holiday spirit.

It's not exactly the modern day equivalent of Ralphie from 'A Christmas Story' in his pink bunny suit, thankfully! The Swift onesies were much more seasonally appropriate, and cute.

Swift made her red flannel jammies -- which remind us of Snuggies -- look good and so did Austin. She must have realized the humor of her attire, captioning the image: "Matching Christmas onesies is a thing that's happening right now."
