How should I spend part of my bonus

How should I spend a small amount from my bonus? I have a decent bonus this year a work and want to set aside about $800 just for me to use… i could really use a better work wardrobe and that could easily eat up 300-400... I’m also coming up on my 5 year wedding anniversary… so something fun like a small trip sans children could be fun… and then there’s the hot air balloon ride. I’ve always wanted to do that but I think it’s ridiculously frivolous.

🤷🏻‍♀️

I’m already adding to my 401k and my HSA with the remainder of the funds. I don’t know how to use the rest. I’m not great at treating myself. Any input is appreciated.
