White dress

"Ok dear, today I need to do a test or two on this white dress" said rarity.

Fluttershy took the dress in her hand and went behind the screen. She slowly pulled down her skirt, exposing some pink panties and folded it up before laying it down. She pulled off her white T-shirt, folded it up and layed it next to the skirt. she looked out seeing Raritys outline in the screen waiting expectingly. she blushed at the thought that Rarity could make out her outline and quickly put the dress on and stepped out blushing a little.
