Need HELP asap! plzzz

i have my fitting tomorrow and i need a crin0line (super full) that has an elastic waist band. i went last night to the place where i know has them and they are all out until next week!!! if i do the fitting with a slip that is slightly different, the hem could be wrong

has anyone seen elastic waist bands on the crinolines at any bridal salons?

my bm mentioned bridal reflections but she got hers there 10 years ago. ill call when they open though.

tia!!!!
