Zadig & Voltaire Star Print Long Sleeve Crinkle Dress

The care tag has been removed from the dress, which I believe is also where the size would be listed. There are no flaws, rips, or stains. I am a true size large, and this fits me but is a little tighter than it’s meant to be, leading me to believe it’s a size Medium. Pit to pit measures 21” Waist measures 18” Shoulder to hem measures 34” I included the size chart from the Zadig & Voltaire website for reference bc there’s no stated size on the garment. From Nordstrom: A starry motif makes a celestial statement on a long-sleeve dress made from sheer, crinkly fabric. • Front button closure • Spread collar • Long sleeves with button cuffs • Sheer • Lined • Belt sold separately • 100% viscose • Machine wash, line dry • Imported
