Wedding Dress
The legendary Wedding Dress is attire typically consisting of an exceptionally ornate, snow-white princess dress with incredibly detailed lacing and patterns, often incorporating flower motifs which might mature a bouquet of flowers held by the wearer. It is often paired with a transparent veil, diamond jewelery, and a diamond tiara. Anyone can on sight tell the difference between a white princess dress and a true Wedding Dress.
Across seemingly the entire universe, this particular outfit has exceptionally high status and even outright reverence. While there is no rule it can only be projected by the most powerful sluts of all—Ωmnigoddesses and perhaps Penultimates—it does not seem to be inherently exclusive to them. Rather, a true Wedding Dress can only be projected when a slut is experiencing sustained and exceptionally powerful love and devotion for specifically You. Some even say this can dress in its truest form can only occur if a slut's love for You is "maximum" (as if there could ever be a limit to love for You!).
Even for the vast majority of us who aren't (yet) able to achieve this dress, the mere fantasy of wearing a true Wedding Dress is incredibly indulgent and heart-racing. Such dresses are often featured in particularly flattering paintings of revered figures.
