As I said, it's lazy because it's merely a slight variation. While you get two unique shirts for the Streetwear set, you only get one shirt in two versions with Leisurewear. It's a perfect reflection of SE maximizing their revenues. Minimal effort, maximal profit.
I wouldn't say anything if this was sold for the price of one outfit. Don't understand why people defend everything SE does.
Also, this is not a real life wardrobe, it's pixels, so your comparison is nonsense. I can't dye my shirts in RL in every color of the rainbow like I can do in the glamour dresser.
