This pajama set is absolutely great! They came beautifully packaged, nestled in tissue paper in a high quality gift box with a ribbon. The silk is soft, smooth and lustrous, all the seams are stitched evenly, and these pajamas look and feel like luxury.
As for sizing: I would have sized up to an L since I prefer my pajamas loose.
Overall, these pajamas are as gorgeous and luxurious as expected. I would not hesitate to recommend them, but would suggest sizing up, since silk is not stretchable.
