I called Promotion a few days after getting my wetsuit with concerns about the fit. They were so amazing! The size I wanted was out of stock (8T), and within minutes they offered to make me one, customizing the size slightly just for me! :-)
Seriously?! Who does that anymore?!
I'm thrilled to report that it fits wonderfully! Very snug but not to the point of "I can't breath." And with enough length and flexibility to FIT.
Now I need an unseasonably warm day for a test swim. ;)
