Shop NYC Top

I just moved to NYC and I am not used to this kind of humidity. For people that work in suits how do you guys commute to your job (preferably the subway users) in this heat. I feel like if I wear my full suit I will sweat it out. I see some of my coworkers wear their regular clothes and change in the bathroom but I don’t want my clothes to be wrinkled or carry all my clothes in the dry cleaners plastic walking through the street and then on a crowded train. How do you do it?
