You don't need that many patterns. Nat Gear will work in every situatuion spring or fall, but that's up to you if want to wear a different pattern for each situation.
It's not like that, I just buy whatever is cheap at the end of each season when things go on sale. Wal-Mart is especially good about marking prices down to get rid of excess inventory. I probably have too much, but when a pair of pants is 5 bucks, I just grab 'em.
