You can order it at Dutil (custom order). Or, you can buy it online from Tate and Yoko!
I missed out on the Green Selvedge which I really wanted... Now with the greencast, it seems kinda similar.
Ultimately, I want a fade similar to these :
Fade Friday – Naked & Famous x Blue in Green Weird Guy (9.5 months, 0 washes) | Rawr Denim - Home of Everything Raw and Denim
Which I think the hemp one gives, but I want to know how the greencasts turn out too
