good post elli, I often wonder the same.
I lounge around in my sweats and baby T's most of the day.
And when im just running out for a errand, I'll put on jeans and a decent T. But dont stress about my makeup.
I also wonder, cause alot of guys like the casual, not trying look..while others like their girl to look tip top all the time.
I think If you look like ur not trying..is normally when you're at your hottest.

JMO.
