According to the article, the study entailed using avatars with or without luxury logos branded on clothing.

Suits can be luxury goods, but the study didn't explore that. It's unclear at a glance if this was actually about status given the methods. There could be other reasons people don't favor corporate-branded clothing, considering that wealthy people don't just wear polos with big corporate logos on them. Maybe it telegraphs poor taste, or that boosting luxury companies makes it seem like you're trying too hard to show that you have money (I make a distinction between this and someone who plainly looks high-status owing to their choice of wear). The obvious thing to include would have been avatars with non-luxury brands, it's possible that would have repelled as well.

On the other hand, every piece of heavily-branded clothing could be considered "luxury" in its own way and the only difference is social class, demographics. In low-culture you'll see Crooks and Castles, Fox Racing, Adidas, etc
