Seventh Coordinate Sexy Dress Brilliant Style is the evolved form of the Seventh Coord Sexy Dress worn by Bell Renjouji in Pretty Rhythm Rainbow Live. It goes with the Seventh Coord Sexy Shoes Brilliant Style.
The dress turns red and is coated in glitter. The lining on the top and bottom of the chest turns into purple shiny material, with the top of the chest adorned with a red rose and a floral design. Instead of black shoulder straps, the user gains a three-layer ruffled sleeve for the right arm, coming in dark purple, white, and red. The skirt reshapes itself to resemble layers of a flower, with the colors red and dark purple to match the top. The choker is now made of dark purple and black fluff with a single ruby gem hanging from it.
After the previous version upgraded, Bell began to wear this.
In the anime the dress appears less glittering than in the games.
