The 5 stars goes to Wayfair customer service! 
I ordered this shower curtain over 6 months ago, it stayed in the package waiting for the bathroom renovations to be complete. When I was finally ready to hang it up, I noticed a big "curve" on one of the embroidered vertical stripe. I thought it's too late to get it replaced but, I emailed customer service (with a photo) anyway and to my surprise I got reply email saying that replacement curtain will be mailed to me. Today it arrived, stripes are straight, I would give 4 stars for the curtain, it has one minor issue: the first and the last curtain ring holes are too close to the edge, you would have to cut the liner to match the curtain. But the material is nice and thick and after good pressing it looks quite elegant.
