Pink Blush Maternity

Erika • Mama to a sweet, energetic 2-yr-old boy. Expecting #2 in August 2015!
Have you shopped at Pink Blush Maternity? The clothes are cute and inexpensive, but I'm wondering how they run? True-to-size, small, or large? If you've ever ordered, I'd love your input! 
I'm ordering a sundress, in case that makes a difference :)
