Whoa, so not what I was expecting. I thought it would be something along the lines of the Disney wedding dresses, more "inspired by" than "little girl dress up". I agree with the Jezebel article. These are not attractive to me at all.
Now, some subtle corsets or slips in the lovely princess colors, that I could (maybe) go for.
Not clicking on it at work, but the phrase "Disney Princess Lingerie" reminds me of a Big Bang Theory episode ( Season 6, Episode 18 "The Contractual Obligation Implementation").
