ModCloth Outer Space dress: L and XL

Bought from Poshmark a year ago. L was too small. XL was good but I’m ready to pass them on. Only wore the XL 1-2 times. L wasn’t worn by me at all, but maybe by previous owner. Both are EUC Size XL 20” flat bust, waist 17, could go to 18” flat, open hips Size L bust 19” flat, waist 15 flat stretches to 16, open hips
