Here is my version of Rarity's Gala dress- modeled after a wedding dress pattern that I drastically altered. I wanted to reflect the original colors and frills of the dress- but make sure it had my own spin.
The corset is fully boned with metal spiral boning with a denim inner layer and satin exterior. The grommets are hand sewn with embroidery floss. The sleeves are a stretch mesh with velvet elastic as the "straps."
The skirt is a massive amount of satin with hand sewn golden flowers, instead of those ugly golden draped rows. The back had a long swirling train of gold trim.
It is the ultimate fancy costume! So much fun to wear, even if most people think I'm every other pony than Rarity.
