Welcome @Cellophaneflowr!
That’s a good mission to be on- I hope the coven can point you towards some fun witchy clothing shops!
I have a rather eclectic sense of fashion myself- my wardrobe is pieced together from clothes I acquired up during my travels. The witchy shops I patron are more herbal/crystal based and don’t really have clothing lines 
But I do know that @MeganB and @Silverbear are both very talented witches who I believe sometimes carry clothing in their shop inventories:
You can also check for clothing shops mentioned in the Recommendations Category or visit Coven Member Shops to see the talents of the coven.
Good luck and blessed be!
