1920s cocktail dresses

Hi sunny coast!
I am recently engaged, and looking to find a bridal shop that stocks alternative styles (think BLACK gowns) and also in plus size (up to 24/26 as I don't know bridal sizing) and one that stocks quirky colourful bridesmaid and flower girl dresses also. 1920s cocktail dresses
I live in Gympie so the journey down would need to be fruitful so asking for suggestions in advance!
Thank you kindly in advance ? ? ? ?
