My fiancé quite likes me in my kilt, I think it's because it's the only time I am very concious about colour coordination - something she holds very highly!

She was 100% in favour of me wearing it for our wedding - not sure I'm looking forward to the July Illinois weather wrapped in all that wool though!! In fact because if the heat I was musing over wearing a Jacobean shirt but that "wasn't dressy enough". If I wanted to wear it more I'm sure she'd be fine with it.

Keys, I'm sure in time your wife will come around. Especially when she sees positive reactions to your kilt.
