I literally wear jeans everyday. Unless I wear a skirt or a dress, of course. My workplace is pretty casual so we wear jeans but I try to dress it up and wear dark-washed jeans with a cute blouse or shell/cardigan combo. Either way, you can usually see me wearing jeans for all occasions. I work in jeans, hike in jeans, ride horses in jeans and even sometimes go to the beach in jeans (it's true).
They are just so versatile and work with almost any top. I love that I can wipe a little dirt on them and you can't tell (perfect for being at the barn). Mostly, though, I love how they make me feel: confident, stylish, sexy, and yet still modest.
I set out a skirt or dress to wear to work nearly every day, but 90% of the time when I am getting dressed in the morning I pull on jeans instead! Just hard to beat comfort!
