You probably could if, y'know, you used her complete definition, which is 'this is how hot you will be if you use this product.' Which is her point.
If the product made the person hot, they wouldn't need to use hot models now would they?
As for the rest, I'm no longer clear on what your points are or what you're arguing, could you restate?
Many products are marketed using a very simple idea:
Sex sells.
Take a product, slap a hot chick with big titties near and it sells like wildfire. I know it, you know it, everyone knows it. We're not breaking new ground here.
If you take out the product... let's say Axe spray where women get drawn to men wearing it like magnets and replace it with a political platform and suddenly it's "You can't do that! Only the platform should matter!"
Are guys supposed to go "Wow, that politician had an excellent platform and I am in no way swayed by her looks.... oh look, that beer has titties. I shall now buy some"?
What I'm saying are the people who are bothered someone is looking at a politicians looks should also be bothered if someone is looking at a model's looks, or an actress, or an ad girls.
You absolutely should look at the clothing's quality. It's called advertising. It can be "this product will make you attractive" or "this product will make you smart" or "this product will make you look patriotic" or whatever else. In this specific instance, where they want you to buy this particular shirt, they think that the best way to sell it is to make you believe it will make you look better. If it was a less crappy shirt, they might market it as "this shirt will last FOR ****ING EVAR."
But you didn't say that. You said a model's attractiveness was a deciding factor. That's why there are no ugly male models, right?
"look how hot I am. This is how hot you will be if you use this product."
That makes no mention of quality or anything like it.
The hot chick in the beer ad has nothing to do with the quality of the beer.
If clothes made people hot, you wouldn't need hot models, would you? You could use anyone.
