Sandro Green White Ludmila Dress Women's Linen Blend Cut Out Size XS?

This is a piece that was used for renting by Rent the Runway. MSRP is $490. The fabric is imperfect around the ring; it's been repaired but the fabric makes it hard to fix perfectly - this is pictured. Rest of garment is in great shape - seems to be a bit worn. Please ask for measurements if unsure about sizing. Stock photo included to see how the garment lays accurately. No size tag, my best guess is XS. Laying flat- Pit to pit: 15" Waist: 13" Not a lot of stretch in fabric.
