have you soaked them? washing/soaking keeps your jeans healthier, but at the same time you risk the deep contrast in the fades. it's a toss up, longer lasting jeans or quicker lighter fades. if you have soaked them and stuff, repair the blowouts as fast as you can so they don't keep growing until your balls are hanging out lol
All jeans will shrink after a soak whether sanforized or not - you will find that the waist will shrink 3-5% but if you go TTS you should have no problems with the waist. The length will also shrink minimally, between 0.5"-1". There's no issue with hemming them before you soak, but keep in mind you might want to leave 0.75" or so to cater for the shinkage.
Started my Unbranded back in November 9, 2010. It's been about 6 months, and I decided to do a cold soak. Indigo Skinnys, Size 33. Before waist: 33.4 in After soak: 32.2in Shrunk 1.2 inches. Soak in a bucket of cold water for ~3 hours. After, I agitated it a little bit, poured out that water (was nasty yellow from dirt and starch), refiled bucket, and stuck jeans inside just to rinse. Hung outside until dry. It was very stiff after drying, and could stand up by itself! I'm wearing them now, and they are getting soft with every way. Actually smell worse than before lol. Ok, now the pictures. Before SoakAfter Soak A little wrinkled, cause I shoved it into a buckle to soak. Will smooth out with wear.
