This was an imagination in a RP with me (played with Annie and Mariette Lee) and my friend  KameHame

After Mariette had a wardrobe malfunction, she was exposed that she wears her My little Pony underwear (That will be a crazy imagination if anyone made those. X3).

Annie was surprised from her underwear that she wears, she imagined what if she wears her own MLP underwear.

For her imagination, she likes to wear an underwear of Twilight Sparkle, because she's my fav character in the show. ^^

Twilight Sparkle: Hasbro/Fyre-Flye (aka Lauren Faust)
