I noticed in your post about your shopping trip, you were looking for shirts that emphasize the girls whilst hiding the belly chub.
I bought this shirt this weekend, and I adore it. It's also on clearance.
It's SO soft and comfy, but super cute. the scoop neck is a little low for wearing to teach, but with a cami underneath would be fine, IMO. But you can also be super casual with it with some cute jeans and flats.
ETA: they also have it in red and gray.
