If one were to be sent back to the year 1969 - perhaps due to an accident with a time machine, or a confrontation with an evil wizard - I think a Nehru jacket could be acceptable.
Although even then, I don't think it would be a good choice for inclusion in a regular work rotation, unless one were employed at a somewhat alternative workplace.
If memory serves, Darwin once wore a Nehru jacket to work - he was a senior associate at a prominent Madison Ave. advertising agency - but it was only because he was under a spell cast by Endura, or maybe it was Serena, and in any case both Larry Tate and the firm's client regarded his choice of attire as being entirely unprofessional and inappropriate. So clearly we'd have to be talking about a work environment less conservative than an ad agency. Which pretty much means the entertainment industry, in Southern California.
So, if ridethecliche gets sent back in time to Hollywood, circa 1969, he might be able to successfully incorporate that Nehru collar into his work rotation.
Otherwise, unless he's working in India, I'd say no.
So, ridethecliche, which of the two is it? Do you know a mad scientist working on a time machine, or have you pissed off an evil wizard? Oh, and do give James Bond and Honey Rider my regards.
