What I'm going to wear tomorrow

So, yeah.
Yesterday I've got a present from my dad, it's a hairband! But it's different to combine, so I want aks you guys for help!
I want to wear this tomorrow, but I'm not quite sure about it..
What do you think about this hairband and outfit?

                       And a detail from the hairband -my face was really crappy-

                                                                    Lots of love,
                                                                    Jessica ♥
