Just got my first pair of Momotaro in the mail - 0701s. I've had raw denim before, but these are beastly! My wast is 29.5, and I got a size 28 (only size left for a great price on Revolve). I can get 'em buttoned up barely, but their definitely gonna have to stretch in the top block if I want children someday. I usually don't soak my denim, and I was hoping I could go that route with these, cuz if they got soaked, there's no way they'd fit. I'm planning to just wear them as much as I can and not wash them for a long, long time. Any ideas as to how much stretch I can expect? I'm pretty damn active lots of walking, skating, etc. Basically I just really wanna keep these and make 'them work for me, and any help would be much appreciated.
