I’m so sorry! I have found that Poshmark has really fast shipping, so long as the seller sends it, they usually arrive in 1-2 days.
Maybe something like this would work? It would probably still need a hem, but if you have a crafty friend/relative they could probably just trim it straight and leave it in hemmed and nobody would notice.
There’s always the option of a tulle skirt and a cute sparkly top if you want that bridal vibe!
Sending you good vibes!
