Who knew a strapless dress looked even better with a t-shirt? Kate Moss was on to something when she styled her embellished, strapless LBD with a t-shirt layered underneath.

Now all we can think about is how we can transform our own cocktail dresses into seriously cool outfits with the help of our favorite tees. Not only do they offer a little more coverage, making them day- - and, dare we say, office- - appropriate, they also have a lot more dimension than your average party dresses. We've put our outfit fixation to good use and styled up three easy ways to get the look. Just click on to shop and channel a little of that Kate Moss cool.
