Tiffany's unboxing notes, I am the Pella manager of 9Lilas Boutique I try on everything to make sure the fit is perfect! I am an XS and wear a size 0/1 bottoms.
"True to size. The 25 (0) fit me great! Just enough stretch with a great mid rise fit that helps keep your jeans in place all day long. Great distressing detailing in a cropped skinny fit."
