How to NOT collect sales tax for clothes in Pennsylvania?

Pennsylvania is exempt from collecting sales tax on clothes. In the settings, I added the collections from my store to override the sales tax for those items. I also added my state and my tax id. But none of that seems to work. I still have to go item by item and uncheck the “charge taxes” to all of the clothes I sell, which is a pain to do. I have already had to refund taxes that were charged for clothes because I hadn’t unchecked that option for those items yet. Is there an easier way to set this up? I’ve tried to look for answers, but I haven’t found them. Please help.

Thanks.

Did you ever find a solution to this issue? I am a consumer who loves in NJ and have requested a refund from a seller who has charged me taxes on Clothing. Their response to my request was basically that Shopify forces them to. There must be a way where exempt items per state can easily be identified.
