Looks great! Just as advertised. I got the largest size, XXL, just to be safe. I would rather have it loose than tight, especially for pajamas. It’s perfect not too loose. I could have gotten even smaller, but I’m happy with the size. I usually wear US small, but sometimes medium if I want a looser fit. My measurements in inches 34-26-38.
The Pyjamas are pretty small but very nice. I bought it for my 9 years old niece (142 cm & 36kg) and it's a bit too small for her. It was no need to contact the saler as everything is as expected
