I am researching how to start my own clothing line of women's and
junior yoga-type pants and jeans.  I need info. regarding the initial
steps in doing so.

My questions: Can I use stock clothing and put my own label/brand on
it? If so, where do I purchase this type of apparel?  Please explain
how I can do this and give web sites for vendors/wholesalers.  I am
looking for trendy apparel that I can modify with my design. Thanks!
