Blue Jeans from Zara, purchased at Smaralind mall in Rekjavik Iceland. Mens USA size 31 from Zara. My boyfriend is typically a size small in men's pants and these fit him perfectly. I can't find this exact pair on Zara's website, but according to their size chart, it should be around: Waist: 15.7" Hip: 17.7" Front length: 41.3" Front rise: 10.2" Back rise: 14.6"
