I wanted a light top to provide a little coverage for casual days with the kids, going to the park, taking walks, etc. I thought a light chambray would be great. With the right shirt I could also tuck it into a skirt and wear it a little more dressed up. I was really surprised to find a great option at Old Navy of all places so it's inexpensive enough to buy a few of (important for all those "special" kid moments), and bonus points for working well as a nursing top!
I bought the dark color and this lighter one as well -
One more selling point, it's long enough to wear with leggings or skinny jeans. The holy grail of shirts? Long, light, nursing access, neutral color, cheap, washable, hmm. You decide!
