I work in a business area near the beach so i see problems with tight fitted shirts, both on men and women, and skirts or dresses that are on the shorter side. If you wear tight shirts just bring a t shirt with you to change into and if you wear dresses or skirts just bring a pair of workout shorts with you and put them on under your dress/skirt in the bathroom when you get to the office.
But don’t worry. In 20 years I have never not been able to treat someone properly because of what they are wearing. :)
