>>89120071Gray (Timidity) for the first on the top row. It's the skimpiest.
Purple (Passion) the next one, with the hearts covering the nipples.
Orange (Rudeness/Laziness)/Brown (Sloth) for the third on the top row, since it covers the most, and it could just be a regular outfit ripped to look like lingerie.
Green (Bravery) for the dress-looking one with a huge gap-y stripe on the middle
Yellow (Knowledge) for the one that's closes to her regular outfit, but sans the cloak.
Pink (Happiness) for the last one, because it has like a skirt, and she could twirl in it.
This is all based on just now visiting the TT wikia, so I could be dead wrong on everything.
