Hahaha, I think it would have been more sexist if they had been topless and actually washing laundry. I thought it was a cute, albeit a corny way to attract male attention, or should I say horny?......, but cute nonetheless.
The true test is just how many men will want to buy seimens washing machines, or if they even realized that was what the commercial was marketing, funny.
Might I add, the ladies WERE quite lovely to look at.
