Did you ever feel the need to change your style as you entered your 30s?

I (29F) turn 30 in about 5 months. I’m pretty excited for a new chapter in my life as I believe my 30s will give me a new career and life experiences since I’m currently unemployed after graduating from my PhD a couple months ago.

However, something thats been bugging me is that I don’t feel like my style has evolved a lot as I’ve gotten older. I usually just wear a plain tee with jeans and Vans or Birkens, but I’ll usually buy my stuff at Tillys and Sun Diego. I think those stores have a good selection for my style, which I guess could be described as more coastal/granola-ish. This has been how it is since I was a teenager, although I don’t think I dress like a teenager. However, my friends that are younger than me (26-28) keep talking about how they want to have a more mature style and get new pieces. The style they want to start having is more conservative. Hearing them talk about this more mature style makes me feel immature considering I have no desire to dress like that outside of work, but yet I’m the one actually entering my 30s soon.

Have you ever felt the need to shift your style as you get older? Is it normal to keep the same style you had in your teens/20s?
