The first case I got for my Rose Gold 6s was Spigen's liquid crystal clear case. It's the one I've had the longest and use the most. Last month, I had a discount from eBay, so I ended getting three new cases. One is a super-thin one with a clear back and rose gold sides (top and bottom of the phone is exposed and it feels like it's be very easy to drop the phone with it on), a Caseology clear and rose gold case and another rose gold case that even covers the front of the phone (haven't used that one at all because I really don't like it). Most recently, I even got a rose gold battery case, although I have yet to use that as well.
