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.
