Dammit,I thought about posting that myself but it just seemed so blatantly obvious.
Was Bowie a celebrity when he wrote Space Oddity? It was his first hit, wasn’t it?
I always thought “whose shirt you wear” referred to sponsorship deals, as if he’d promised to wear a Nike shirt into space. Athletes and media stars are always doing endorsements, and I thought the idea was that astronauts are stars like them.

While athletes and movie stars have appeared in commercials for decades, nothing really equivalent to the modern practice of endorsements existed in the 1960s. Besides, I’m pretty sure that the astronauts then were prohibited from doing any commercial deals. Active NASA astronauts today certainly are.
The world of the 60s was very different from today’s.
I don’t think he thought the astronauts had endorsement deals. I think he was cynically comparing them to people who did. Artistic license and all that. Weren’t star endorsements of Chesterfields and the like as old as radio?

I don’t know about Major Tom, but Custer wore Arrow shirts.

Although, if I remember correctly, the Mercury astronauts all received free Corvette Sting Rays (and maybe other astronauts as well). Pretty darn good advertising for Chevrolet.
