My daughter bought her three children costumes from Pottery Barn, and the quality was pretty good. The little girl is a Spider Fairy, the oldest boy is some kind of Dinosaur, ...but the youngest boy's Superman costume has the "Ruby" brand tag on it, which apparently is the brand sold by the big-box stores...it does not even have the Pottery Barn label on it...and price was significantly higher than at the big box stores. He had taken it out of the package and loved it--would have been devastated if she sent it back-- so she just ate the experience...but was furious to say the least.You can't leave reviews on Pottery Barn's website, I guess, and Customer Service just gave her a polite brush-off. Quality did seem OK, even on the Ruby branded Superman outfit, but these were not the higher-quality, "better" costumes that Pottery Barn seemed to be describing. DD is swamped at work, does not sew, and finds that her kids wear their costumes multiple times...so was trying to access a better product that they could wear longer and more often without the costume falling apart. She's not thrilled, and won't purchase from PB again...but the kids all do love their costumes.
Sigh, the writing is on the wall. Grandma had better get the old sewing machine out next year.
