I am size 16 top so bought a S/M and M/L in another design. The s/m is slighter shorter than m/l and both dress fit great.
They are very versatile easy to throw on and comfortable, just like a nightie but with a fab design that you can wear to shops. The dresses would be great for summer holidays for beach, pool or even camping. I would rather pop on this dress than a sarong over my swimmers. I think they would be great for travelling also, no need to worry about creases.
Best feature they have pockets, yep just have to remember to empty tissues when I wash.
