if you really want to preserve the color, there are ways to keep them dark as long as possible. i would give them a very long soak to get as much of the starch out of the denim as possible, this will make them softer and less prone to creasing so easily. be sure not to agitate the water much though, because that will cause more indigo loss. and don't wear them every day or when you will be dooing a lot of activities like walking around and moving a lot and such. you could also keep them hanging flat on a hanger to minimize creasing and steam out the wrinkles and creases periodically as needed. if you don't have a steamer you could just hang them in the bathroom while you shower to relax the creases. but as i said, this kind of defeats the whole purpose of buying flatheads since they are known for their fading potential. they aren't intended to be treated with kid gloves. there are plenty of solid dark jeans out there that are not raw which would suit the purpose you are looking for much better. and even lots of other raw jeans that are known to not fade as easily.
