Is it ok to use part of your tax return as a splurge?

There's such a big push in the PF world to be disciplined with your tax return. To invest it or put it towards debt instead of spending it on something fun like a lot of people do. Well, what if I want to save a proportion of it and then spend the rest? That's certainly what I"m leaning towards right now. If I save 2/3 of what I'm expecting, that will bump my post-graduation relocation fund by 50%. I'm not sure what I'm going to do, but right now I'm thinking that my summer wardrobe is about 3 years old for the most part and could use a little make-over. Hmmm...just thinking about it...
