The more I look on these pictures, the more usual or “everyday” the latex looks. Indeed, the style is pretty formal, the latex is not too tight, the clothes is not “revealing”, the shine is not bold. Of course, you can make latex shine as black mirror, but in this case (we are talking about the office style) this is not the goal. The idea is to make it look like leather or heavy silk.
Hm… Interesting idea is to compare latex to leather, PVC and coated lycra.
