I recently bought a short-sleeve chambray, and I love it. I think it'll become more of a favorite than the current long-sleeve chambray I have from Old Navy. (I did not, however, include it in the collage, but you can find a look featuring it here.)
Chambray: Old Navy
(Obviously, you won't wear the hat for teaching, but I love the rest of the silhouette.)
Dress down a fancy skirt with your chambray for work. (I'd wear different shoes, however. A pop of color, perhaps.)
Wear it with one of your printed skirts. Tuck it in or knot it in front of your skirt.
Layer it under or over one of your dresses. To tuck it under like I did here, knot it and then tuck the knot under.
Here is a cute fall/winter look for a casual Friday. If you're lucky, your mom is as awesome at crocheting as mine is.
Leave it untucked with a pair of colored skinnies and tall boots. Again, this look works well for a casual Friday or even an in-service day.
If you're not into skinny pants because they feel too informal, try a bootcut pant like these with your chambray. I like this look as well for a casual Friday or in-service day.
Okay, this look is fine for a day that's not casual. You can tuck yours in, but I liked the visual interest of the knotted shirt. Choose your own adventure. I added heels for more sophistication.
As you can see, chambray does not have to serve just your casual Fridays. Tuck it into a skirt or button it over/under a dress, and you have yourself a dressier look.
Which one would you actually wear to work?
