My 3-yr-old daughter received this as a gift for her birthday.  She's no pixy, but she's not huge either, and it was VERY tight on her, so I doubt a 6 year old can fit it comfortably.  The tutu fell apart after 12 hours -- the satin waistband detached from the tulle.  Unless twirling counts as rough wear, I'd say this was poorly constructed.  I sent two messages to Sydney So Sweet directly, trying to get a replacement or at least some kind of acknowledgement and NOTHING.  So ... crappy construction and crappy customer service.  I already don't like tutu/fairy/princess stuff, and this just furthers my opinion that companies like this are preying on daughters.  Boo!
