Wouldn't this just be the best dress for the holidays in a warm climate? It's vintage, but it's in a good modern size: Bust 39-40", waist 30. If you want it you'll have to hurry, though, there's only a day left on the e-bay auction. Bring money, it's on the pricey side. But so cuuuuuuute! Perfect for the hourglass lady.
The seller's store is called bombshellbetties; it's worth a look.
