I'm pretty sure I saw the ones you are talking about at my local Walmart. Really dark pink with light pink hearts that are kind of...outlines? Like they were drawn with a marker or a paintbrush? They only had S,M, and XL. However the other color variety of the same robe on the rack had 2x ones, so I bet they were just low on stock of the heart ones. I will check back next time I go and see if they restocked any 2XL or 3XL.
