I also ordered the 3x in hopes of it being a loose perfect fit for me. Wrong. It fit very awkwardly. I could feel restriction when I moved in it. Just by an inch or so. Wish they had a 4x/5x to move up to. I'd definitely say anticipate ordering 1-2 sizes up.
I love the color and the feel of the satin but it runs small. If you have a large chest, size up or it will fit funny. I think if it had some stretch to it like the other pajama sets have then it would be perfect.
This runs extremely small. I got a 3x which is my normal size and it fits like a medium. It's not true to size and the plus size options need work! They are about 3 sizes smaller than what they should be and it's so hit or miss.
Sexy and comfortable fit
I am a 38DDD /40DD and wanted this to fit loosely like it's shown on the model, I ordered a 2XL in the top and bottom and they are perfect! The satin is so soft, and there's plenty of room. It's perfect to sleep in and also easily comes off if you don't wanna sleep :) RiRi, you have done it again!
