哈哈。这个答的好玩。替无忧辩护两句

I assume noworry is in industry and holds a pretty high position. brand name suits, shirts, shoes are part of one's image, especially important for men. His friend moving to the Federal goverment. UNless he is in a position of "chief" etc. brand name is not that important or not appropriate, since everyone knows federal employee does not earn high salary, but being fit is. Thus, one spends thousands to get dress-up, one uses the money to get fit. Both are working towards the same goal, image.
