A maternity button down shirt is a wardrobe must-have, but this style can be tricky during pregnancy because of the bra-revealing gap buttons can create. Fear not - the No-Gap Maternity & Nursing Button Down Shirt eliminates gaping with MARION's exclusive concealed under-button placket (patent pending). A mama doesn't need a lot in her maternity & nursing capsule. This gorgeous, sustainable workwear classic belongs at the top of the list.
