The difference in clothing

Today I was able to go for a nice run outside in the morning.  I was finally able to try out a long sleeve dri fit shirt that I found at Target.  As I was running, I was feeling confident.  And really I feel like it was because of the clothes I was wearing.  I felt like I looked like a runner, wearing running clothes.  I wasn't just wearing whatever old tshirt that was clean.  I really need to do some serious shopping and get myself some more actual running clothes so I can always feel like I felt today.
