Oh, Kate, you shoulda stopped trying to wear your shorty shirts. You wore this when you still had 5 weeks until your due date. There was a decided lack of shirt stretch happening. Good try, lady. Next time, stick with rotating your small handful of maternity shirts and stop trying to sausage-encase yourself in your XS collection. It's not a good look.
Hope I learned my lesson- don't wear stuff optimistically, I just look like the Stay-puffed marshmallow man if it's too tight. Hehehe, it was a cute concept, but the fit didn't work in my favor. At all.
