depending on whether humans are still involved in the consumption side of the economy, there may be jobs for humans in marketing. Robots will be better at coming up with the campaigns, and robots might even be better glamour models (shouldn't be hard to build a size-0 or 36-24-36 robot). Still, I suspect that some irrational element will still be present - humans will probably be more likely to buy a product which is endorsed by a human.

Compare this to Milli Vanilli - the music is still the same, but once people know it's not "real" it goes way out of fashion.

One could even speculate whether humans could be trendsetters for robots, but I don't think this is very likely.

(P.S. Actually, I think the most likely scenario is that humans become obsolete and extinct. Remnants of our civilisation will live on, but not us. This answer works with the OPs assumptions that robots are utopically benevolent.)

If your ideal for a glamour model is a size-0 or 36-24-36, it shouldn't be hard to build a robot with those specs. (Using examples which seem to be common in the marketing industry, and trying to avoid judging whether they are valid ideals.)
