I have to say my fiance is approving and at times, downright approving, though recently, as I've actually begun to wear one from time to time, she seems to have taken the tack that it's great in 'appropriate' situations.

These situations seem to be defined as either 'very dressy' (e.g. our upcoming wedding or an occasion where a suit would be appropriate such as an orchestra concert) or 'very casual' (e.g. a walk in the park... she understands the comfort issue there). Aside from that, she feels the only appropriate 'casual' wear circumstances are when we might be going to a real pub or perhaps bumming around the house in the summer as an alternative to shorts.

I'm sure she'll come around as she gets more accustomed to it.
