This would work a whole lot better for me with some transparency, like a video archive of Sray making the sweater, a little bit of following her through her day, the ability of independent people to come in and visit / interview Sray once a month or so and include those in the video archive. Keep all that and get a link to it with purchase of your sweater.
Otherwise Sray might be some dirty sweaty unschooled kid walking 5km barefoot through untreated sewage to work under a tin roof making 3 sweaters an hour with machinery designed to mimic handmade details, complete with "attractive" human hairs to embed here and there, and $399 of your $400 purchase price is going to the factory owner and his distribution channel.
