There are plenty of people who don't want their cleaning help to dress below their standards. This gives them the ability to ask that they dress accordingly, and they're putting their money where their mouth is.
You can't make your cleaning help buy all new clothes just cuz not to your liking.
I'm a pretty liberal Jew and I respect this quite a bit. It's no different than providing a uniform to waiters in a catering business. You are allowed to have a dress code in your home and it's honorable to cover the cost of your help's uniform.
Although, like @Dan, I still don't understand why there are no pockets.
And I should add, that if "Preserving the Kedusha of your Home" is the goal, then presumably the bal habayis is paying social security, and appropriate taxes and paperwork for the help. Using an illegal and not paying uncle sam is probably less kadosh than seeing a little elbow.
