So I'm so outta touch, but I just discovered Mildblend in Wicker Park this weekend. For denim heads this is by far the best Japanese Denim selection. They even have a union special to do chain stitching on. Among the brands carried they had:
The Flat Head
and a bunch more. They had other stuff too, but I was just surprised by their denim selection. And they didn't just have a pair or two, but stacks on stacks of them. Dudes were super nice to, asking about my PBJs and stuff
They also just stocked some Arcteryx Veilance recently too if anybody in the neighborhood wants to try.
