I absolutely love when I see other Rose brides from Utena! Of course I adore Anthy, but it's great to see the other characters get love! Especially when Kozue and other characters don't. Personally I love Kozue: she's complex, and her relationship and love for Miki is what made me really get invested in her. Not something you see everyday.
Anyways, before I drabble, your outfit looks fantastic! The dress looks great and the sewing job you did for this look of high quality!
I don't know the character you're cosplaying, but I've completely fallen in love with the way the skirt drapes over the petticoat The whole outfit looks like really high quality Also; you're beautiful.
