Zara is hit or miss with me, fit and style wise. I have some pieces that I absolutely adore - a long black wool coat, and a white skirt prettier than all the others from the white skirt trend last summer. And some nice basic teeshirts and yoga pants and stuff. I wouldn't say it's poorly made, not just great quality. 95% of it holds up well for me. And I like their quick turnover.
Their tailored pants fit me horribly though, and the inseams in their jeans are so long I have to have them all hemmed, which is annoying. And I wear a 32" inseam, so I'm not a total shortie.
