I almost bought the size 18(36W) but measured my waist first just to be sure. My waist measurement was 38 so I got the 18/20(38W) assuming it would be the perfect fit. I also have another pair of Lucy and Yak jeans in that size that fit well. They ended up being so big that they fall down to my hips. I measured them and they were 42inches. If the pants measured to 42inches why not just label them as a size 22? Why can they never do anything correctly? Why can't they make a size chart that's accurate? Why can't they make clothes in the size on the label? Every other company can do this just fine. Even typing this review was unnecessarily difficult because for some reason they decided to make the comment boxes in a grey colour and the text in the same color so you literally can't see what you're typing unless you highlight your text. If there's a bunch of grammar mistakes that's why.
Anyway, I live in Australia so the return process would be too much of a headache to go through with so it's probably best just to stop buying from this ridiculous company.
