Found an interesting article on Dailycandy about "stylish sweatpants." I am all about trying to sneak comfort into dressing up but a few designs went to far. Here is an example:
3.1 Phillip Lim
Wool Flannel Lounge Pant
These pants are the most beautiful and comfortable sweatpants. I love love love everything to do with Phillip Lim. His style is amazing and classic. One day I might be able to afford something at a 3.1 Phillip Lim sample sale - eyeing everything in his Fall 2010 collection.
Just a thought.
