For pants someone mentioned you can get plain looking KEVLAR liner jeans which will cover your legs and ass. this is really important. If it get cold, get over pants (textile or leather). Yes over pants getting baggy but from my experience is I usually get cold on legs but not upper body. I wear plain black leather jeans (levis looking). If it get colder, you can get thermal underwears. You can also wear chaps but I don't think it fit your bike.
as for boots, I don't recommend you wear fashion looking biker wannabe boots. Those boots offers you no protection. Get a pair of sturdy boots and wear it. No matter it's in summer or winter, you need real boots. I wouldn't sacrifice less protection for anything. yes There are some real motorcycle boots and good looking. Search brands like Dainese (italian) or ICON (portland, oregon). ICON has a line called ICON Thousand. I like it a lot. So get another pair of casual shoes at office.
Also for night riding, get a cheap ugly reflective vest 5 bucks from ebay. It's ugly I know but you need to let other people see you. Always assume you are invisible and people trying to kill you.
