These shorts are super comfy and cute! I'm a size XS/S and they fit perfectly. I'm not sure if they could be considered one size fits all.
I really liked the material and it wasn't too short and feels really comfy!! My only complaint would be that the waistband IS a little tight but overall great product!
The culottes are really nice and fun to wear with different colours of shirts. In Europe I have a trousers size of 34 and this piece was perfect. It's not to long or too short and it has elestic waistbands. Really nice.
The beige culottes are cute, but the waist is too tight! And I'm petite... (5'0", 42 kg). I would have loved to wear them, but they felt so uncomfortable that I had to return them.
