Should I start spending on myself ( nice clothes, maintaining friendship with upper class people, eating out)?

Should I start spending on myself ( nice clothes, maintaining friendship with upper class people, eating out)? For context, I’m from South Asia ( 28F). I’ve been working for a few years and saved up some amount. I come from a modest background but recently I’ve come in touch with the upper class. I’m looking to get married. I’m currently a bit lost. I’m not sure if should change my lifestyle a bit since I can afford it. A part of me wants to keep saving for rainy days but another part wants me level up and get inside the upper class society.
