Wicca does not have a set code for clothing. Street clothes, hoodies, t-shirts, jeans, etc... are just as acceptable. If looking for clothing with a witchy feel to them, then there are several online stores, and many metaphysical shops that sell clothing that would/could be used and seen as "wiccan clothing".
A good place to start would be to buy a beginners book such as Wicca: A guide for the solitary practitioner by Scott Cunnigham or Wicca for One by Raymond Buckland.
