I took a size M ( 1.58 m and 42 KG) and it fitted perfectly. The pyjama is soft and feels comfortable to the skin. It was packaged nicely and it was delivered within two weeks to Holland. Everyone, don’t doubt to buy this! I’m very satisfied.
The version I got was a glossy silky finish instead of the cotton version of the pajamas. It's still comfortable but it's not like the pictures.
