I found this by accident in sunset and I thought I'd share. Basically, the puffer jacket + the babydoll dress makes a puff sleeve dress! You can add things around the neck to obscure the seam where the items clip into each other better, and it works well with bracelet things (I used dv cuffs) around the bottom of the sleeves to make it look lacy.
Here's the result!
Sorry, my character turned her head at the exact wrong moment ;v;
