Sci-Twi may have the fall formal dress but remember that this was a dream sequence; Sci-Twi may have seen the picture of Princess Twilight in the dress and her subconscious put it in her dream closet. Maybe she should ask Rarity to make one for her if she likes it so much!

As for the portal, I believe that it always transforms transients into the same default form with the same clothes (in the pony-to-human process), so the original fall formal dress may have been transformed into an Equestrian equivalent or it may have just been erased by the transformation process.
