"Pretty" is pretty subjective, but perhaps you could give us a better idea of what you're looking for: What type of music do you prefer? Is there a price range you're looking within? Are you looking for isolation with the closed design, or is that just an aesthetic?
I hear the AH-D2000's are incredibly comfortable, and personally I think they're rather attractive, but they don't isolate well and might not have the sonic qualities you're looking for. The D5000's come with Mahogany cups, which I find even more attractive, and make up for some of what the D2000's lack, but they cost a touch under $400 (new), which might be out of your price range.
The Beyerdynamic have a good reputation for comfort, and the velour pads could be to your liking. The DT770's are closed, seem to be middle of the line in terms of sound quality, and go for around $200.
ATH A700's are cheaper, and also come with good comfort and soundstage. Their look is quite unique, though, and I'm not sure if they're "pretty" enough for you.
