Thought sustainable British clothing navy bamboo jersey jumpsuit, size 12

This jumpsuit is super comfortable. The bamboo jersey is super soft. It's like wearing pyjamas! The style is not reflected in the photos, but it is loose all over, except for the waist band. So the top is like a loose t-shirt and the bottom are like culottes. The last picture is to give you an idea of the style, it is the same model in a different color. The waistband, which is the only fitted part, is 17 inches across. Please ask all questions before buying. Thank you.
