If your ultrasound were an x-ray, it would look like this. (You’d still hang it on your fridge though, be real.) The Pregnant Skeleton Maternity Costume Dress is a tribute to all the metacarpal mothers out there – some may call it frightening, some may call it fact, we call it workin’ with what we’ve got this Halloween! Next year’s costumes are gonna be a skele-ton more work, but you’ve got it.
