"I have this in a dark greyish/greenish color with navy trim not pictured here. I don't wear a ton of slips but this one is much more versatile than I expected. I wasn't sure about it, but as others have said the material is not at all flimsy, and it's super comfy.
I have found it looks great under an oversized sweater or shirt. It makes some baggy pieces that I love look more like pulled together outfits!
I usually wear an xs but bought this in small, and I'm happy with the sizing. It does show anything underneath pretty distinctly so layer wisely. Definitely best as a base layer."
