I have bought my USA Kilt second hand. The seller's wife would not let him wear it. She would not even allow the kilt to be inside their home! Thus, he had to get rid of it (or of her).
When ordering it, he has used the option of having belt loops for men's ordinary 1.5" wide belts, rather than for wider, regular kilt belts. It is fine with me. Whenever I prefer wearing a kilt belt, I simply don't use the belt loops (which in fact are not for the belt but for the sporran strap).
I should have ordered an inch or two longer, however. With its 20" it, even at jeans waist, is to the short side.
Quite a few, no doubt, will say it is too short, and worn at true waist it certainly is, at least from a traditional point of view.
Despite basically too short, I really like my USA Kilts Casual and do wear it a lot, low or high, with different types of belt, with and without a sporran, mostly without, with kilt hose up to the knees or scrunched down, or with just ordinary knee high socks, as well as with short socks and 'invisible' socks or no socks. On my feet I have sneakers, boots, or on rainy days, rain boots. At low temperatures, I a few times have worn it with leggings or tights around my knees - like men wear them together with running shorts etc., so why not with a casual kilt?
