Order up a size if you want it baggy. I sized up in the Cosy Pointelle-Knit Romper ($25) because I don't like sleeping in tight pieces, and I'm so happy I did. You can see just how loose the fit is around the legs and body, which is exactly what I was looking for. If you prefer a tighter fit, I'd recommend ordering your true size.
