Fun unsolicited social psych lesson: in terms of persuasion, spontaneous messaging is catchier but thoughtful messaging is more likely to have a stronger long term impact. Often best to use both.
It's not always the same level as debate, but the idea is there. Why buy? It's got safety standards. It builds strong bones. It's good for the environment. Good? Ok now here's emotional music and a celebrity you like.
Research shows spontaneous messaging without the cognitive side isn't going to sway attitudes in a meaningful way, although the latter might be needed to get attention (and most won't work if someone is already decided, then you really do need debate lol).
That said, I'm pretty sure the average ad is just trying to keep a brand in public consciousness, since that's taught in marketing programs. Some research on associative learning might support that but I think it's weak at best.
Flannel's plaid disrupts any curves so it's pretty good for covering up bellies in particular. A big reason I'm a fan of the season of flannel (plus scarfs are nice, too).
