The black jackets show off your wife's blonde hair the best.
I like the first one. The second one is OK, but personally I don't care so much for the blue shirt showing at the waist. But what do I know - I'm just a stupid male who doesn't know anything about fashion (my wife just wears scrubs - both at work and much of the time, after too).
I would add just a titch of front-side lighting to bring out the texture of the black suit. Things disappear into the blackness .. and then her hands appear almost out of nowhere. I also like the expression on your wife's face in the first one the best (although that's subtle and hard to pose). Just a hint of a smile.
Remove that blue light thing from the wall outlet behind her. Yeah, my house is full of stuff like that too. But you don't want it on a business card IMHO. Probably an irrelevant suggestion if "she's having head shots done...", which implies different location, different photographer.
Tell your wife she is very pretty.
