I've done a little bit of modelling for Pistache Streetwear (not professional), they send me free tee's and I take photo's for them, pretty sweet deal!
They do have some cool designs for both men and women, so if you have an urban style, it's deff worth a look.
'After working for brands like American Apparel & Quiksilver, brothers Nick & Jamie Bennett established ‘Pistache’ in London, 2003. Since then, Pistache has been on a mission to produce the best quality screen printed t-shirts available, with minimum impact on the environment & maximum impact when you wear them. Pistache screen prints everything by hand with eco-friendly inks. This gives every t-shirt a unique quality that can’t be mass produced by machines. They also create limited edition graffiti caps, skateboards, stickers, mixtapes, canvases & other artwork.'
