There is a method to the madness when it comes to the usage of details. Ideally, you'd place them on the areas you want people to zero in on. Yes, you can place them wherever you'd like for the sake of expressing yourself, but wouldn't you like to maximize your detail to get the attention you are seeking? Isn't that the point of it all?
Details vary from fringe to embellishments, but they all have one thing in common, they stand out. If done right, details can completely distract from areas you don't want to draw attention to. Love your boobs, try a rhinestone broach on your lapel, got killer legs, try a pair of cropped skinny jeans with fringe ankle detailing, have an hour glass figure to die for, show it off with a stellar applique mini dress. See where I'm going? Details are a huge hey look at this sign, use them to your advantage.
