Fits Everybody High Neck Bodysuit

I love the Fits Everybody Collection, it's like nothing I've ever worn before. It's mind boggling because the material is really fine yet holds up to an everyday wear. I got the size M knowing that the fabric is stretchy and it fits great, I'm sure a size L would have been fine, just for reference I'm 5'4, 150lbs,size 10, 36D or 34DD.
