Well, that depends on the dress code for your job. We have an real lax dress code here where I work. I'm an electronics engineer by trade. My desk is in an air conditioned office but the engineering lab is in an open warehouse with no air condtioning. It can easily get up to 90 with the humidty about as high. (Ohio in summertime). In the summer most everyone save a few office people wears shorts and T shirts. That being the case I carry a couple changes of clothes in my backpack which conveniently hangs on the seatback of my 'bent. A quick trip to the washroom to dry off and all is well.
