Take one fairly ugly poncho.

Add a cowl, a very large belt with chains (so punk) and random tassels, et voila!

It is now completely ugly.
Take a dull, lumpy, sweater dress and slap some doilies on it (and a belt).

Now it's "Blondie meets Granny."
Why make boring classic sweaters when you can liven them up with big, pointless braids?

Better yet, add epaulets.

And a belt. Mustn't forget the belt. You don't even have to knit it!
Take a nice textured knit jacket. Now throw in some gigantic fun fur cuffs (are they even attached to the sweater?) and a button-crusted belt.

It's office chic with a little cavegirl Victoriana thrown in.

It's amazing what some out of scale buttons and winning the Super Middleweight championship can do for a plain mohair sweater.
Remember folks, when in doubt embellish it. Then add a belt!
