A:AnswerNo, it will not fit. I preordered my Kate Spade case for the iPhone 7 Plus, it arrived and the packaging said iPhone 5.5 and the case wouldn't fit my iPhone 6 Plus case. I don't know why Best Buy has it listed as an IPhone 7 Plus case.
A:AnswerYes! I have a 1 and 3 year old who have dropped this thing multiple times and so far it's been protected! I think the purpose is more more about style, but it has definitely protected mine more than enough!
