My Dad was in the army in the 60s. He gave me a few pairs of NZ Army trousers that are worn at the proper waist. They also have a lot more room in them. They are probably the most comfortable trousers I have. I do hope you would not think I look silly. But then, it doesn't really bother me if you do. :-)

Most trousers that are available in the shops don't have nearly enough room in them to be comfortable even when worn at the hips. I know, if you try to wear this type of trousers at the waist, it is very uncomfortable.
To clarify, I was speaking of normal pants worn too high, "grandpa-style". Most modern pants simply aren't made to be worn at the waist, and when worn that way, they look silly to me.

Because my hips are not level, if I have to wear pants (i.e. when I can't wear a kilt!), I'd prefer to wear fitted pants like the ones you describe. They're incredibly hard to find, though. The only pants I've seen that are made to wear at the waist are military surplus models and reproduction 1800s style clothing. I really like the look of 1870s style pants worn with suspenders and a linen shirt. Sadly, with modern "fashion" being what it is, this is seen by most people as being as 'kooky' as wearing a kilt. People think it's a costume. It just happens to be a costume that goes over easier here in my area of Texas.
