many have suggested that you not mix crossdressing and your job. Others have pointed out that you didn't ask if you should, you asked how. Others got sidetracked and started insulting each other.
If you choose to go ahead and "out" yourself at work, you might as well do it all at once like pulling off a Band-Aid. Get up early enough, get a good shave and makeup job, put on your forms, padding and wig and a dress or blouse and skirt appropriate for your job and just waltz in like you own the place. It might be uncomfortable for a while but that's better than just confusing people by wearing a combination of male and female clothes. Have a new name ready like Jenner did.
Remember though, you'll have to do this every day and you might have to shave and touch up your makeup in the middle of the day.
