Having bought several dresses from Mr. Walton's supermarket if you know what I mean, I must say, I am impressed with these.

Most Disney princess dresses for $20 in the local super-mart are flimsy and last about 2-4 weeks in my house with 2 girls age 2 and 4 who play with them regularly.

I've had these almost a year and apart from some minor wear they're still going strong.  Better quality than the Disney dresses.
