Fashion outdated

I feel like no matter what I do, how expensive I buy, how much I research, I end up looking outdated in my outfits compared to people my age. Side note: I went to catholic school all my life and now I wear scrubs for work. I also have no friends. I’m 27. I also deleted social media for my mental health.

So I just am curious how will I really know what’s in style and how I can revamp my wardrobe?
