Honestly, you shouldn't care about labels
As long as you're conscious about your spending habits, and you buy things because they legitimately make you happy (not out of compulsion), it's all good.
If you feel some kind of guilt over your purchases, take a step back and:
1. reevaluate your budget, set rules for yourself regarding the amount of money you can spend in a specific time frame
2. take into consideration that it's just a mobile game with virtual clothes. Its shelf life is maybe 3-5 years, and someday it will all disappear and mean absolutely nothing. It's all about your very temporary happiness so
3. decide what's truly worth spending on. Events and clothes return, chances reset, and stamina reloads, there's no rush. Skip the event if you don't really care about the suit, be cautious with pavilions, and don't aim to be a completionist (because it's simply not possible)
