What is the basic information someone your age needs to know about the garment industry?

Outlet stores are made from cheaper materials. Yes, they might have that little flag, pony, or even branded metal plate but it is not worth it. You want to be rich not look rich.

Sizing is not always agreed upon between brands so don't beat yourself up because you went a size up and didn't meet your goal. This is because most likely the store that your shopping at makes smaller clothing than your usual store.
