I have the same sunflower jersey in purple, and I've washed it quite a few times (gentle cycle, woolite) with no problems. I have a few others of theirs: sleeveless signature, sleeveless solid in blue and in black, the Wild Cat II leopard one, long sleeve solid in blue and in black - oy - I better stop before I look pathetic - but anyway, they've held up okay with gentle machine washing. But, I don't use the dryer - I drape them over my sofa to dry!
