What sort of work do you do? Is there a place to change? Frankly two miles is not even beyond walking distance so I would just wear my work cloths. My office is professional casual meaning kakis, Dockers, button up or polo shirts (with company logo are appreciated) and I keep a sport coat at work for going out at lunch if needed with a customer. And we can wear jeans on Fridays in the summer. They want leather shoes or at least not tennis shoes or sneakers.
The point being, if you wear a suit and tie you may have to change but if you can wear buisness casual just wear that. And if you can wear jeans them perhaps just do that. I do not know your, uh, circumference but I love the skinny jean fits or slim straight Levi type jeans and some have Lycra in them. The skinny fits do not get caught in the chain and roll up nicely also.
I do not get to bike commute but I keep a bike in my office for lunch time rides to nearby eateries and coffee shops etc. When I have commuted, such as during college years, I wore what I wore to class. My new office bike is a Raleigh Sports 3 speed I am overhauling.
Good luck, I would forgo the cycle specific MAMIL look for a two mile commute. Now, out for a sporting ride, by all means Lycra up
