What is the Calvin Kline Commercial Really Saying?

Over the weekend, I went to my cousins house to watch the Superbowl. While I was excited to watch the game, the commercials are something I always look forward to seeing. I find the commercials to be quite amusing, however, in class today we looked at commercials more closely, and not just their entertainment value, specifically the Audi commercial. After this thoughtful discussion, I began to think of other commercials I could further analyze. The one that immediately popped into my head was the Calvin Kline commercial.

In this commercial there is a man, with the "perfect body", modeling Calvin Kline underwear. What struck me most about this commercial was that it was appealing to a woman's audience. During the Superbowl, about every other commercial was directed towards a male audience, such as, the Ram, Bud Light, and M&M commercial. My question, then was, why was Calvin Kline trying to persuade Women, and not men, to purchase Men's underwear?

The only logical explanation that I had was woman are buying the underwear for men.

As such, with this reasoning in mind, I wonder does America view women as the ones who just do the shopping? The ones who take care of all of the domestic needs, like clothing? The ones who's sole function is to take care of their husbands?
