Why isn't it working!?

I have been working out really hard for about a month now. And really watching what I am eating. So I don't understand why I am not losing any weight, or even just toning up. I really don't care about losing any weight as much as I would just like to tone up. I don't care about the number the scale says or the size on the tag of my jeans, I just want my regular clothes to fit better. I tried on my prom dress before I tore it apart for Lyhna's costume, and it did fit. So I shouldn't be so upset about this. It is really hard to put in so much effort, but not see any results.
