That odd “dressed up” Twilight fashion style now has packaging. She’s part of the Through the Mirror line, a Walmart exclusive to tie in with Equestria Girls. She comes with a paper or plastic skirt that you can color in. This was posted on EqD.
The Rainbow Power brushables are starting to pop up on Taobao in their packaging as well. It seems to be a main line and should be out in any store that carries pony. Throbulator posted these on The Round Stable. Check out two others after the break.
