Everyone is so excited, since today is Barbara's 18th birthday! All is ready for a great party: the house is stuffed with balloons, party lights and other decorations, a huge 3-layer cake with pink strawberry icing is waiting in the kitchen and all the friends have received their invitations and can’t wait for the party to start. But the girls cannot start the party because they haven’t yet decided what to wear! Barbara has seven new dresses and she is still hesitating on which one to choose. Her sister are thinking about wearing matching outfits, but they can’t decide on the color. One has already found three cute purple dresses, but other one thinks blue is more appropriate, and third one insists on them all wearing pink. As you can see, the girls have quite a dilemma! Maybe you could help them?
