"Match" is not the same as "go with." I learned that from Clinton and Stacy.

Granted. But I still don't know what the problem with them matching is, and also what the problem with them not matching is.

Bah. I did something to my knee. The one that was injured when I was hit by the car 16 years ago. I was in Borders, took a step, and there was sudden pain. I had to fight the urge to just let that leg collapse. The next three or four steps were the same way. I tried walking slowly and carefully and it was fine, except once ever few minutes a step would result in pain.

Dunno what I did to it. A few months ago I hurt my knee when I ran across the street to catch a bus. After two weeks the pain went away.

Now I'm wondering if I should have a doctor look at it.

First off, rest, ice, compress and elevate. If it's swollen, you might want to wait a few days to take it in, just so they can see more easily what's wrong after the inflammation has lessened.

I always recommend having doctors look at knees. They're crappy engineering.

Cool.

Yeah. Almost as if some Intelligent Designer took the knees of a quadruped and, um... watched from the side as they evolved into knees for a biped.

Dammit Tommyrot, do you have to go blabbing all my secrets? You'll keep your mouth shut about design flaws in the future if'n you know what's good for you. Like, nice appendix you've got there. Be a real shame if anything were to happen to it...

Ow.

Oh, you guys, I think the ibuprofen helped me! Except walking up stairs SUCKED.

Not being Bon, I'll provide my own answer: wearing a blazer/jacket and a pair of trousers of the same pattern/weave/make appears more formal than jacket and trousers that are obviously different. It looks like something you might wear on a job interview, and thus can put across a more strait-laced impression than you prefer.

and also what the problem with them not matching is.

I... don't have a problem with them not matching, as long as they go together. I go through phases where I wear blazers as light jackets for ordinary wear (i.e. even with jeans and sneakers), and own several versatile blazers I'd be comfortable wearing with not-matchy trousers or a skirt for a nice-but-not-formal look.

(One is a grayish tweed, e.g; and in this category I also count my blue leather jacket, which has lapels like a blazer.)

In not-matchy jacket and dress trousers, my coworkers might remark that I look nice today. In matchy jacket and trousers (actually I only own suits with skirts), my coworkers would look sidelong and count the number of minutes I spent at my lunch hour, and make jokes about how they should pay me more.

I have to wear a blazer for work and I hate it. Oddly enough, when I had to wear a top hat for work I loved it.

Then don't wear them. There's no rule that says you have to wear them together. If the occasion supports matching, match. If it doesn't don't. All the pieces on that list have their places.
