I like them alot. I have a pair of somewhat high waist jeans and a pair of the very much high waist pant that express just had on sale. However I am also tall-ish 5'8'' and have a long torso.

Most high-waisted jeans make me vomit in my mouth a little. Some high-waisted, wide-leg trousers, or high-waisted pencil skirts, can work on the right person and with the right tops.
I like them as long as they aren't super high. Most low rise jeans hit my hip bone in the wrong spot and it's very uncomfortable with all the pocket seams and rivets.
High waisted skirts look really good on me, pants I've never tried because I'm short (5'3) and I think you really need height to pull off that look. A fried of mine is 5'11 and she tried on these Nanette Leport high waisted wide legged sailor pants when they first came out and they looked absolutely fabulous on her.
In general I like pants with a higher rise (like an inch or so below the belly button)...but I really hate the whole super-high-waisted pants. I just think it looks stupid and very very trendy. Plus, almost every guy I've talked to think it looks super ugly/un-sexy.
