MISS LULO love letter retro sundress with swallows and envelopes

Gorgeous sundress that’s extremely figure flattering - bought on a whim at a retro and vintage clothing boutique in Rehoboth, DE, and I honestly have nowhere to ever wear something like this, as much as I love it. New with tags. Has a sash tie belt and back ruching. Would look cute hanging straight down or with a crinoline underneath. See catalog photos for same dress in a different color to see the fit Size is XL - fit me like a glove when I tried it on in the boutique - size 10, bust 38C
