Nice fabric, very comfortable set👍🏻
As in the photo. Viscose. XL maximum at 46 size.
The set is wonderful, took like pajamas for sleep. To the body is pleasant, sewn well, all the seams are neat, the fabric is thin, the composition is indicated as 100% viscose, the coloring looks good.
Size XL sat perfectly on my 44 (95, 76,100 cm).
