In Odin Sphere, the price Oswald pays for Gwendolyn's hand is to battle on behalf of the Inferno King. Oswald fell into danger, and Gwendolyn set out to bring him home. Heck yes princesses that save the prince! <3 I love their story, it's so adorable.
How did you make the petticoat? I have search everywhere for a tutorial and can't find one, so I decided to ask someone who had already did a ballbown petticoat! can you give me some advice or instructions sorry to bother you :S
I could give you some tips on specifics, sure! If you pretty much need a step-by-step guide, though, you should check out the Livejournal community "Corsetmakers." They have tons of resources I poured over when I was looking to get into corsetry and without it, I don't think I'd be as skilled as I am now.
