Knowing how to do laundry in college has less to do with the actual washing of clothes than with the correct wearing of them. Certain items of clothing have life spans which can rarely be tinkered with. Understanding these life spans, and therefore getting the maximum amount of wear out of your clothing, is essential to survival. Being the nice guy that I am, I will now relay the immense knowledge that I have in the area of clothing life spans. First, start at the top with shirts.
Shirts are in relative abundance compared to other garments.
They can be bought cheaply at nearly any type of store anywhere. Shirts only go a day under normal circumstances. The fact that they hang up there by those massive sweat glands under our arms almost ensure that shirts are spent after one day of wear. Also, being that your shirt is often the key element of your look for the day, it is really nice being able to wear one that is clean. The exception is shirts that are worn over other shirts.
