Do you have a fail-proof outfit?

For some reason, I feel the most confident when I'm wearing something casual: Jeans, T-shirt, cardigan, Converse sneaks--done. No fuss, no frills, just chill. This is the real Ellen Collis. Will the real Slim Shady please stand up? And, put one of those fingers on each hand up. Umm, sorry. I've been listening to a lot of Eminem on my iPod recently. I digress.

So I don't know what's up with the mean mug on my face. I guess that's just what you do when you're leaning against a brick wall. This is what I wore to work yesterday at the boutique. I was worried it might be a bit too laidback, but I felt so good, I just couldn't bring myself to change. It's just so...ME. I love not second-guessing my outfit choices, and that doesn't happen often. Score!

This is my fail-proof everyday outfit. Slip on some Ray-Bans and I'm good to GO. Now all I need is a fail-proof nighttime look. Once I figure out what that is, I'll just wear it to every single event I go to, and I won't care who's giving me the stank eye. So what's your fail-proof outfit? When are you the most comfortable in your own skin?
