Amy Gardner's Outfits

I'm watching season 5, in which Amy Garder is serving as Abbey Bartlet's Chief of Staff and I have to ask, how the heck was she allowed to wear some of the stuff she wore in the office on the average work day? The suits are fine, but the tops under the suit jackets show an awful lot of cleavage for someone who works at the highest level of government. What are others' opinions on this?
