First, they are just jeans..so you wont mess anything up. That's the thing with raw denim, they all come out unique to it's wearer and what they do in them. You can wash, soak them when ever and how often you want. With my N&F I soaked them earlier than most would but I'm going to be washing/soaking these more than I'm going to with my APC's which I'm going to hold off for as long as possible.
But I suggest getting a pair of Naked & Famous even if you're paying full price. I think average pair would cost around $150 so save a few more bucks or order from ********* with a discount code which is usually 20% off. Blue Owl would be another great place. They both offer exchanges so you can return for different sizes if need be. You can also find good deals in the classified section.
