Personally, I think an environment where you can wear jeans and Ts IS cool. I think, Fernando, that this is what ASal may have been getting at, not that the turtleneck itself was cool. However, if that floats your boat ...Anyway, on to the question at hand. I'm not a lady, but I reckon this applies irrespective of gender. Our dress policy (unofficial, as we have nothing written down) is to take the lead from the client. Find out early, preferably before you go in, what they wear and then dress to suit. If you can, try and look a touch more professional that the client staff to mark you out, but don't go overboard so as to make the client staff uncomfortable. For example, in the jeans and t-shirt clients, don't go wearing a three-piece suit.Wear what you look good in within the context of the client environment. However, packaging is everything in this business, so never look unprofessional. Whatever you wear must always be clean, coordinated and in a good state of repair.That's what my mom told me ...
