Having my clothes sold at a boutique or store?

Thats a really idea for a girl of your age. If there are any clothing shops in your area that locally owned, like small boutiques. Ask them if you could put up just a few of your designs, and usually people will start wanting you to make them stuff. You'd Probably have to make them yourself but don't makew a whole bunch of one thing make seceral different things at first then when people start to order them make more of each item. Does that make any sense to you? You could also start up a mwebsitte to show off the clothes
