Dress Idea

I have been thinking about this fit and flare dress for 2 days non stop.  Should I just buy it? We currently don't have set NYE plans or another occasion I could wear it. I've also been thinking about how to make it using these 2 McCalls patterns. I already have the skirt pattern and have been dying to make a skirt with it. All I would have to do is add the top to make the dress and I could pick out my own fabric. I'm really getting into this project. Now all I have to do is find a party to wear it!
