I’m starting up a clothing brand and i have the concept in my head but i need a designer to make it for me. I’m curious if the designer makes it for me does the logo belong to him or me? because i’d be placing this on my shirts at first. Do i have to buy the copyright from him?

Would it be better for me to draw it and for the artist to refine it, making it look more professional so in that way i have all the rights to it because i did the original concept drawing of it?
