The 17-year-old "Frenemies" star always takes multiple snaps when getting ready for red carpet appearances so she can see what she will look like in paparazzi photos, making sure her outfit isn't see-through, reported E! Online.
"The biggest thing is you have to take flash photos of your outfit before you step out wearing it. It happens to people all the time, where the outfit doesn't look see-through and then a flash goes off... It's all out there," the actress said.
