Mermaid Petticoat?

Hi Girls -

I have a mermaid style gown and I need a crinoline/petticoat to go under it. I am going to dye it pink, but I have to find one first!

David's Bridal, where I got my gown, doesn't have them for my dress, I don't think. I don't want to buy one online because I think I need to try it on with the gown.

Do you ladies know of a bridal shop in Nassau (preferably) that has mermaid petticoats/crinolines?

Thank you!!!!
