I like Jcrew's blythe blouses for stilk shirts. You might also look into their casual blazers - like the schoolboy. You can roll up the sleeves to make them a little more casual, and I think they look great with jeans.
Thanks! I ordered a Blythe in tall. I'm usually a 0 but it was too short so hopefully the tall 2 will work. I have the navy school boy, any suggestions for what looks good under it? I always feel like a flight attendant because i dress so plain but it looks cute on other people.
