Welcome Oliver, I can only reiterate what everyone else has said, it's either a non event or really great ie one night in a local town my mate was waiting for me. He was wearing a newly aquired Amerikilt, a guy came up to him and said 'my mate got married in a kilt' Mick replied 'really.. I got married in a church'. A bit obvious but smiles all round.
As for my first night I didn't have time to be nervous, my kilt arrived on New Years Eve while I was at work. I walked into my house at 9pm and out in a kilt at 10pm.
Thats not to say I'm never nervous, thats part of the fun. No one would sky dive if they weren't a bit nervous.
Be confident and enjoy yourself,
Cheers Rhino
