How do you Collaborate with global brands?

Hello Everyone!

Glad to be on this forum, and pleasure to e-meet you.

A question i have always wanted to ask was how to reach out to big brqnds for collaborations? Its always so cool when I see collaborations like the one between Danielle Cathari who I believe was student at the time and mega company adidas.

There have been many more collaborations like that, and i am curious to know how those connections are made? if anyone has had any experience , please share your story.

Thank you,

Julia.
