I’m obsessed with these trousers, they’re so floaty and fab! I sized for my hips incase the fabric was delicate (I didn’t want to add any extra stress to the seams) but I don’t think it was entirely necessary. They’re lovely and loose but still fit fine. They sit lower on the waist than what I usually prefer (my waist is 14 inches smaller than my hips!) but I loooooove the roomy hips so I wouldn’t have them any other way. I’d say if you’re between sizes you’ll be fine sizing down, but if you’re after the ultimate floaty trouser then sizing up or sticking with the measurement guide shouldn’t be an issue either, just be aware that these are WIDE 💙💙
