Yes, GAP denim falls more towards Kia. I think I saw one pair on a forum that faded decently well, but it took a very long time. Also, just because something is selvage doesn't mean it's quality. Nothing bad happens if you wash more frequently, they'll just fade differently. When people go for very long stretches without washing, it's usually to get higher contrast fading. If you were to wash them after every few wears, you'd end up with virtually no distinguishable fading outside of the theighs and ass getting a little lighter than the lower legs.
