What brands work with micro influencers?

I have 2.1K on Instagram and I’m looking to collab with clothing brands. I reached out to a few like whitefox boutique but I’m always declined given that I’m a smaller creator. Anyone know of any clothing brands that work with micro influencers like myself? It’s really difficult finding brands to collab with when you aren’t big on the platform. I did reach out to many and never hear back.
