We've all seen the great LEAD SISTER t-shirt worn in a concert by Karen. It was actually a joke of Karen's that she had made. There was a translation mix-up in Germany where it was supposed to be "Lead singer" but was put as Lead Sister.
The back reads KAREN 1/2
LeadSister.com was named after this very t-shirt and so we have been offering it for quite some time now. And LeadSister.com forums very own NOKS shirt! Members of our forum typically catch NOKS so we should have a shirt letting people know!
