Cake - Seriously, any event that involves a nice cake makes me feel extra festive and celebratory. Birthday parties - Cake

Weddings - Cake

Pretty much anything fun - Cake

Even my favorite cookies (that I've had to limit to the holiday season) are nothing more than boxed cake mix, whipped topping, and powdered sugar. I could eat an entire batch simply because they're like eating cake...which obviously makes me feel festive! Shoot...I may have just talked myself into making cake
Sparkly Clothes - I know some people see it as gaudy or too over the top, but sequins, beads and rhinestones make me feel festive and just amplify my enjoyment of celebratory occasions. I was debating about wearing a sequined dress tonight, just to make the evening more fun but (this is technically a good thing) everything is now too big for me. Of course, DD19 borrowed my silver jumpsuit and left it up in Oklahoma. Even one of my holiday tops for this year, which is plaid, has these ruffle sleeves adorned with pearls and rhinestones. I'll come up with something.
Jewelry - This is really hitting home this year because it's tied into one of my "get it done" goals I'm fulfilling (vs. procrastinating and making it a resolution). Jewelry has all kinds of feelings beyond the value and quality for pretty much all people. Of course, it can be more casual daily wear pieces or bold statement pieces that you might save for special days. Most of my fun stuff is accessible and could be worn tonight if I so choose, so that's good...but I will also put it on tonight knowing that I got the ball rolling on a trio of jewelry related projects I've been sitting on for a while. I'll spare you the novel, but by Saturday, I 'should' be able to wear a couple of my most beloved daily wear pieces after years of them sitting locked up, broken, and unwearable. They're also pieces that are bold enough to be worn for festive events as well as every day, so extra excitement there.
