Find my own style!

I'm usually not ready to take risks. All of the unwanted attention that I could get! And what if experimenting with style makes me look crazy? And I'm in my 30s already. I know that everyone keeps saying, that that's no 'too old' for things like such but, yes, people will talk. But looking at all of those girls going to parties, concerts, raves looking so out of this world gorgeous with their creative outfits I feel so jealous. I do have FOMO because these are probably the years of my prime and I don't use them to the fullest.
I want to try new things so bad but I'm so afraid of looking like a person, who lost sense completely 😢
