You can leave some tendrils or blows out of the bun to make it look less severe. This is a great style in the work - which allows easy change at the end of the day.
Au Natural: Another great idea is to simply go natural. Whatever the texture of your hair can be just a few minutes on some frizz serum or gel to relieve a little control and continue with your day!
Braids: Braids are in fashion this year and will be fun, but mature at the same time. You can do a French braid; braid half a braid hanging loose braid or a dirty side. Anything goes with a braid.
