The power of T

You are about to learn a precious secret. No, not The Secret, or whatever self-help magic is making somebody else rich today. This secret will help you get to know a woman quickly, accurately and without pretense. It will give you the insight of a dozen deep conversations at a glance. And it's as easy as one, two, tee.

Yes, the only thing more revealing than a woman's T-shirt is, well, a woman without a T-shirt. But that's a different post. Alyson Hannigan's rubber ducky tee was a gift from John Ritter after he guest-starred on Buffy. Needless to say, Hannigan treasures it.

Hannigan is one of 15 celebrities pictured in EW.com's "15 Stars In Their Favorite T-shirts." You can see Portia de Rossi in her prophetic Iggy shirt in the latest Best Lesbian Week Ever.

Chloë Sevigny is adorable most of the time, but in her Groucho tee, she's irresistible. As if we would ever even think of resisting.

An EW photo editor gave Jane Krakowski the shirt off his back during a 30 Rock photo shoot. She couldn't seem to remember why.

Tina Fey loves this Who shirt that used to belong to her brother. According to Fey, "I was never the most knowledgeable Who fan, but I'm a big fan of my brother." Lucky brother.

Sites like T-shirt Watch can help you gain insight into other famous women. At Worn Free, you can find favorite tees of rock & roll legends. And this entire blog is dedicated to Celebrities in T-Shirts.

My favorite T-shirt? I got it for my birthday a few weeks ago from a couple of friends who said, "This shirt is you." They were right.

Now that I've revealed my innermost self, it's your turn. What does your favorite T-shirt say about you?
