how to carry a wedding dress like dhakka pants and tail gown ?

hi dear . these days bridal fashion is changed and every other bride is wearing either dhaka pajamas or shararas with tail gowns or long shirts … my question is how do they manage to sit on the stage in tail gowns and please if you can .. share some pictures of brides wearing tail gowns and their sitting pictures..
