All of this actually takes some planning to a detail that most people just do not do.
For example, I bought one t-shirt with a pocket at the end-of-summer sale, went home to wear it for awhile, then went back and bought 7 more in many colors. I knew that they would be perfect next summer and I had trouble finding them in the past. They are perfect.
My son-in-law was shocked that I bought 8 t-shirts at the same time.
