Facehuggers,
I don't think she was an android. Look at her collar it is up like Peter's Collar. That would be a mamangement style, Peter with a single breast pocket like a suit jacket and Vickers having none. David's shirt is more utilitarian in nature given he is an android that would make sense.
Most corporations have a dress code. Like where I work. They require management to where button ups or company polo's, dress slacks, belts and fashionable steel toed shoes. Engineers (like myself) are required to where the same, unless they are working on the shop floor then they can where jeans, steel toed boats and a lab coat kind of like what David is wearing but blue.
