CT, just to throw in my support at this time - I am unable to compare notes since I have been single for eleven years, am ageing and have to answer to no-one else. On the other hand, I have been a kilt wearer for over 55 years and a full-time one for the past 7½ years. As other here will tell you: trousers, even shorts, are not to be found in my home at all!

Could it be that your SO, when thinking of The Kilt, visualises it only in its full-dress form (ie: as for a Wedding) with the Prince Charlie jacket and waistcoat, dress sporran, etc., etc.? Has she actually seen you or any other kilted guy dressed casually - in a Polo or T-shirt, with hose folded/scrunched down over casual boots? Show her the many photos in the top three 'stickies' in the "Show us your pics" part of this forum. There she will see examples of just how many great ways our kilts can be worn. There are over a hundred further photos in my own photo album, linked below.

Unlike any other item of clothing we may have in our wardrobes, the same traditional kilt can be dressed up for the most formal occasion AND can be dressed down for the most casual. Please try to show your Good Lady that Kilts are NOT necessarily uniforms or costumes - they ARE, quite simply, garments!

Good Luck.
