Ashlee Simpson embraced her demure side recently as she hit HBO's annual post Emmy Awards party in Hollywood.
Turning to London Fashion Week fave Temperley London for her evening look, Ashlee opted for a stunning floor-length dress.
The silk number was delicately detailed with tiny crystals, beads and embroidery. Gorgeous!
But we've spent some time swooning over this dress before, as Katy Perry first favoured it on the red carpet in April.
The pop songstress went all whimsical in the embellished dress, which she accessorised with layered pearl bracelets.
But who do you think wears the dress best?
