I think of my handbags as the accessory that I use the most, but in reality, that's not even close to true: I interact with my bag several times a day, but I interact with my phone case almost constantly. Even casual friends could probably pick it out of a lineup because it shows up on brunch tables, happy hour bars, on my desk at work, everywhere. I look at it more than I look at almost anything I own, and I'm far from alone in that regard.
Because attractive iPhone cases are almost all pretty affordable (with notable exceptions; we're looking at you, Dolce & Gabbana), picking a new one in a light color or summer-appropriate print is a quick seasonal pick-me-up that might have more of an impact than you'd expect. At the very least, it's something new to spruce up the table on girls' night out. All the ones we've picked below are iPhone 6 cases, but they also come in 6 Plus size, with a couple exceptions.
