"But I don't think this is materially damaging to Sydney Sweeney in any way, shape or form."In fact, I don't think it's a large departure from who she is and what her brand represents.

Critics accused the campaign of carrying racial undertones, with some social media users even labeling it "Nazi propaganda."Other fans defended Sweeney and the clothing brand, arguing that the ad was simply a playful promotion for jeans. One supporter wrote, "Woke advertising is dead. Sydney Sweeney killed it."Fox News Digital's Tracy Wright contributed to this post.
