Costumes to be somebody else

Was just thinking of some wearable costumes for theatre. When I sketched them I could already see fabrics and construction *** it's a professional hazzard*** But I would love to someday make costumes- for people, dolls, mannequins...to wear.. to display...to gift...to sell.
I do make dolls..I guess I can start there.                                                            
I can see blogging about what you have already done makes you think about more things that you want to do. YAY!!!!!
