Fake thing has a big advantage, because it’s much more cheaper than original. Firstly, these fake things can be useful if don’t have a plan to use all fake things in your outfit at the same time. If it's combinated with good style and looks good on You, why not? You can get some fake things, just in case you should pay attention for material quality, some of them look really very cheap (reason of bad material quality). Also if You buy just for casual wearing, but not special events, you can choose for sure something not original. So it depends how you feel and where you are thinking to wear it, what kind of people will be around you. I think much more important taste of style, just 1 or 2 fake things in your outfit will not make people laughing of your style.
