You can buy one from the band – they are available in red or black. I got the black shirt (shock!) as it has metallic silver ink in the print. I’ve tried to capture the sparkly print in the detail shots. The shirts fit really well (I was pleasantly surprised after getting mine as most band shirts are kinda shit), and they are only a meagre $20 each.
If you want a t-shirt you can order them from the band by contacting them at firstname.lastname@example.org. They have paypal too, if that helps.
Many thanks to Sarah-Kate & Li Roadkill for the t-shirt gig photo <3
