I want these jeans from Rock & Republic but I don't have any experience with how their sizes run. On eluxury, it says that the jeans are 2% spandex and to order 2 sizes down. I've also heard that R&R runs big. What's your experience with their jeans? I'm usually a 27 in designer denim. I also want this pair of Joe's Jeans. Nordstrom's says that size 26 is a 4 so I guess I'll get that size. Do Joe's Jeans stretch a lot?
