The Crossroads of the Aether
Businesslike colors, and treat it like a vest - wear it under jackets or cardigans, over a plain colored blouse? I would imagine that if your bosom isn't overflowing the top, and it's not shiny/bright/lacey, you'd do okay if the rest of your outfit is simple and office-appropriate.
(I tend to follow the rule of 3 in work situations - you're allowed three distinctive elements per outfit, and if something's really distinctive, then you only get one. Everything else should be neutral or conservative or both. So you can wear a quirky watch with an interesting necklace and a colorful blouse, but if you're wearing bright red tights everything else had better be a neutral in a classic cut. I'd say that a corset is at least a distinctive element, and may, depending on your workplace and your corsets, count as a Really Distinctive only-one-allowed piece.)
Another large part of a corset coming across as simply part of your wardrobe rather than a scream for attention is your attitude while wearing it. I have brightly colored corsets and wear them with neutrals as mentioned for more serious functions. Though if your attitude is nonchalant, it will go over much better. If you are furtive it will come across as sheepish or embarrassed that you wore this to work. If you keep touching it/adjusting it, you look like you are trying to draw attention to it. And finally, don't make it look uncomfortable. One of the hardest things about wearing tightlacers, is that they tend to start to make your ribs uncomfortable as the day goes along. Similar to wearing uncomfortable shoes, don't let it show that you are uncomfortable or it just draws attention to it. If someone gives you a compliment on it, accept graciously and don't over-do it. If someone makes a snarky comment, of course use discretion since you are in the workplace, but dang you are wearing a corset. Everyone is bound to know you have some attitude. ;)
Kudos on adding this delightful piece to your everyday wardrobe! Wear it with confidence and the rest will follow.
My only suggestion would be to wear trousers with them, in any case. A long skirt would seem costumey, and anything shorter would come off as too promiscuous. Unless either of those are appropriate for your workplace, trousers are a sure bet.
Hm. I'm afraid I have no advice on this topic, but as I have been considering adding a corset to my wardrobe, the information dispensed here has been very useful to me. It also makes me thankful once again that I own my own business and as long as my clients aren't offended by what I wear, then I can be as eccentric as I wish. Oddly, I've found that most of them (my clients are mainly seniors) truly enjoy seeing what sort of getup I might walk in wearing every week. Many of them find nostalgia in the more vintage items, and enjoy the creativity of some of the other style elements. I think they're all secretly Steampunk! ;)
Kudos to you for taking it to the conservative world! Perhaps you'll make a convert of someone!
Be well. Be wild.

And thank you, as well, Greene Fyre! Props are always appreciated, and wouldn't it be wonderful if all these closet steamers would just come out so we could have a much more interesting world of gizmos, gadgetry, and fancy threads? Ohhhh, how I dream!
My sister works for the Ministry of Justice and wears corsets to work regularly.
The trick is to select your corset and style is as you would any other officewear garment - no overflowing bosom or anything to flashy. Generally black or grey in pinstripes, or any fabric you would make a suit of, works well.
Wear your corset over a business shirt or blouse so you're not showing too much skin. If you wear it with business staples, i.e a pencil skirt or wide leg pants and a suit jacket, it'll blend right in :)
