No size tag, but I'd say a 10-12 based on the below measurements
This stunning linen and cotton blend dress is a hefty weight fabric so is incredibly smoothing and needs no slip, making it perfect for the warmer months. Slightly puffed sleeves with elasticated cuffs. V neck with a ruffled wrap and a long tie that can be wrapped around twice.
