Gen Z/Alpha fashion advice needed

Hi all!

I (23F) am thrifting clothes for my nieces (12F) birthday in a few months. I’m aware she is technically Gen Alpha, but I felt like the teenagers of Gen Z might be able to help me out. Where can I keep up to date with what the teens are wearing today? She loves a lot of the clothes I wear but she’s not afraid to be honest when something doesn’t strike her fancy lol. I mostly kept up to date with fashion when I was growing up on Pinterest. Is Pinterest still a good place to start? Are there any popular influencers in your age range or brands that are particularly in right now?

I have a lot of basis to go off of in terms of what she’s taken from my closet (most recently Dr. Marten Mary Janes) but I want to give her clothes she’ll like especially while I’m still cool in her eyes. She loves band tees so I’m looking on Depop for those, and I’m mainly looking for summery clothes but otherwise I don’t have many specifics to go off of so anything is helpful!
