I just got my shirts from Down East Basics. Unfortunately the sizes ran smaller than Shade! So, my Maternity smalls that I ordered are skin tight. They are smaller than my Shade regular small (a little longer but tighter)! Doh. And I'm also sad that the crew neck that I ordered was out of stock so they just refunded my money and didn't send it. So, I'm not sure how the size compares on that. The 2 shirts I got will have to be returned. I don't even know if the mediums will fit me now! I hate clothes shopping online. It's nice that it gives a variety, but unless I know the company and the sizing, it's neigh unto impossible for me to find the right fit on the first try.
Oh, and those Shade mediums have a slightly better fit after having washed them.
