Take a scroll through Bieber's Instagram, and you'll see she's a fan of low-backed clothing. You'll also notice that the revealing cut perfectly frames a tattoo that reads "coeur d'alene." A quick google search might make you think the piece is for a city in Idaho, but it actually has a more personal meaning. "Coeur" translates to "heart" in French, while "Alene" is reportedly the middle name of Bieber's sister, Alaia.
