This is one of my staple casual summer bump styles.  Loeffler Randall makes a comfortable sandal without compromising style; and the white t-shirt from the Gap is made from the most comfortable fabric (& it’s extra long to cover my bump!).

t-shirt: GAP // pants: Motherhood Maternity // sandals: Loeffler Randall, this style out of stock // bag: JCrew, (out of stock), similar options here and here
