Moonblood
The previous mentioned Lucyology have now moved and changed name to Moonblood. Many new designs are now avaliable, and my favorite must be the Egyptian inspired skull tee called Tea Tutunic.
They have many tribal art inspired tees with a modern twist and a really unique design. Most of the designs are hand printed on girly tees, but a couple come for men as well. Prices are between $38 and $42 and are well worth the money.
