If it were legal here in Arkansas, I'd definitely have a fixed blade EDC. (I'd still carry my Commander and CQC7 though!)
Attire is an easy work around if you give it a little thought. A lot of it depends on your climate and your work dress.
In the summer months, I can almost always be found wearing what's known as an Aloha shirt, Hawaiian shirt, whatever.
I'm lucky as my wife will sew the shirts to my specs, and I can pick out my own materials.
I ALWAYS go for the loudest colors and flashiest prints I can find, as I find that people are so busy seeing the LOUD shirt, they don't notice all the little bumps and bulges underneath it!
My wife makes them intentionally loose fitting, as they have to cover a .45 auto, spare mag pouch, and at night, a Surefire 6Z flashlight. I also ask for an extra long "tail" on the shirt, to prevent it from riding up and "flashing" my secrets to the world. This has the added advantage of just barely covering my jeans pockets, making the clips of my Emersons invisble as well.
In cooler weather, I'll wear the ubiquitous "Photographer's Vest" which, to those in the know screams that I'm carrying concealed, but to the average Joe and Jane on the street, it's completely unremarkable.
Concealment is easily accomplished if you just think about it a little bit. "Hula Hula shirts" may not be the answer for you, but there's an answer out there somewhere. Think around corners, you'll figure it out.
