Forever 21 shoe question-sizing

I need something like this but I know with 3 kids I won't get to wear them often so it's not worth spending lots. I saw this which is perfect but it's whole sizes only and I am a true half. I'm a 6 1/2. I know a 6 won't fit but am nervous that a 7 will be too big. Anyone have experience with their shoes. I've never bought from them or suggest another option. I'm looking for nude patent leather platform heels.shoe
