I don't think it's "necessary" for a business selling t-shirts, especially starting out. But it is an option, depending on how you see your business growing.

Setting up some type of business structure (sole proprietor, partnership, llc, etc) is a good idea. If at the very least to help keep your personal income and business income separate. Getting a separate business bank account is a good idea as well.

They said that it was better to register a corp. but then again thats a whole LOT of complicated mumbo jumbo a small starting bussiness like mine doesnt need.

It could vary from country to country (or even state to state) on the requirements/benefits. If your local bank can't handle it, you can try setting up a mechant account online from places like e-onlinedata
