No, I wouldn’t buy them but only because I think they look too small for the model and therefore I’d question how comfy they were - I like big, comfy pants these days.
Otoh, I love that the model is mid size - not too slim and not obese - and probably more representative of many women. If the knickers were bigger and comfier looking I’d be more inclined to buy them as by using a model that size I could see how they’d look on me.
