This dress is an edit of the Flower and Lace Flirty Dress from the EA Store. It does not require you to have the store version for this to work in your game. While I love the shape of this dress, I edited out the funky looking squares, which I happened to dislike very much, added some straps and messed around with the color channels and cleaned up the textures a bit. Comes in presets shown and has 3 recolorable channels.
Comes in both Sims3Pack and .package files.
