I have made this hat pattern a couple times before (here and here) and really enjoy it. It isn't exactly standard brioche; the technique is easier than brioche but still results in a beautiful, squishy, reversible, two-color project, so I love it.
The color scheme I've chosen here reminds me of iced gingerbread, so that's what I'm calling this hat. 😊
The biggest difference this time is that I stopped decreasing after the 48-stitch section to leave the top of the crown open as a messy bun/ponytail style hat. I used a 5mm crochet hook to cast off the knitted stitches into a round of 48 SC, and then worked one more round of SC with a few decreases to get the final stitch count down to 40 stitches.
The language of the video is Russian, but it's easy to follow along with the designer, Katerina Mushyn, as she knits in the video, so even if you don't speak Russian, don't be afraid to try this pattern. She also provides written instructions in both Russian and English in the video and on her website.

It's also helpful to use a row counter that has main/subcounter functionality with this project. I used this free browser-based Row Counter App.
